You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.

[User] Which hardware items have dimensions in the top 10 % of all widths, and what are their IDs, names and widths?

[Assistant]
Let's break down the question:

1. We are looking for hardware items.
2. We want those whose width is in the top 10% of all hardware item widths.
3. For each such item, we want its ID, name, and width.

Step 1: Identify how hardware items are represented in the KG (class/type).
Step 2: Identify the property for width.
Step 3: Find the property for name.
Step 4: Find the property for ID.
Step 5: Construct a query to get all widths, compute the 90th percentile, and select items above that threshold.

Let's start by searching for "hardware" as an entity to see how hardware items are represented.

[Tool]
Top 10 entity alternatives:
1. Hardware (pv:Hardware): The hardware products produced., is subclass of Product
2. hardware chip outline svg?color=#D6AF00&format=svg (<https://api.iconify.design/ion/hardware-chip-outline.svg?color=%23D6AF00&format=svg>)

[Assistant]
The entity pv:Hardware represents hardware products and is a subclass of Product. This is likely the class we need for hardware items.

Next, let's search for properties related to "width" to identify how width is represented for hardware items.

[Tool]
Top 10 property alternatives:
1. width (mm) (pv:width_mm): The width of an item measured in millimeter., has domain Hardware
2. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
3. height (mm) (pv:height_mm): The height of an item measured in millimeter., has domain Hardware
4. type (rdf:type)
5. quantity (pv:quantity): The quantity needed., has domain BOM Part
6. range (rdfs:range)
7. lat (wgs84:lat)
8. weight (g) (pv:weight_g): The weight of an item measured in grams., has domain Hardware
9. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
10. created (dct:created)

[Assistant]
The property pv:width_mm is used for the width of hardware items, measured in millimeters.

Now, let's find the property for "name" to retrieve the hardware item names.

[Tool]
Top 10 property alternatives:
1. name (foaf:name):

2. name (pv:name): The name of something.
3. ID (pv:id): The ID of a thing.
4. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
5. domain (rdfs:domain)
6. label (rdfs:label)
7. phone number (pv:phone): has domain Agent, A phone number.
8. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
9. price (pv:price): The price specification of a product., has domain Product, has range Price
10. created (dct:created)

[Assistant]
For the name, we have two options: foaf:name and pv:name. Since pv:name is described as "The name of something" and seems to be used for products, we'll use pv:name.

For the ID, pv:id is available and described as "The ID of a thing."

Now, let's summarize:
- Hardware items: instances of pv:Hardware
- Width: pv:width_mm
- Name: pv:name
- ID: pv:id

Next, let's check how hardware items are structured—are they direct instances of pv:Hardware, or is there a property linking products to hardware? Let's list some instances of pv:Hardware.

| hw A145 1240844 (prodi:hw-A145-1240844) | width (mm) (pv:width_mm) | 17 (xsd:int) |

[Assistant]
The hardware item prodi:hw-A145-1240844 has the properties pv:name, pv:id, and pv:width_mm as expected.

Now, to answer the question, we need to:
1. Get all hardware items with their widths.
2. Compute the 90th percentile of all widths.
3. Select items whose width is greater than or equal to this value.
4. Return their IDs, names, and widths.

SPARQL does not have a direct percentile function, but we can:
- Get all widths, order them descending, and select the top 10% (using OFFSET and LIMIT).
- Or, count the total number of hardware items, compute the number for the top 10%, and select that many items with the highest widths.

Let's first count the total number of hardware items with a width.

[Tool]
Got 1 row and 1 column:
| count          |
| -------------- |
| 1000 (xsd:int) |

[Assistant]
There are 1000 hardware items with a width. The top 10% would be the top 100 items with the highest widths.

Now, let's construct a query to:
- Select all hardware items with their IDs, names, and widths.
- Order by width descending.
- Limit to 100 items.

We will use OPTIONAL for pv:name and pv:id in case some items are missing these properties.

Let's proceed to execute this query.

[User] In which department is Ms. Brant?

[Assistant]
Let's break down the question:

1. The entity is "Ms. Brant".
2. The property is "department" (i.e., the department in which Ms. Brant works or is associated with).

First, I will search for the entity "Ms. Brant" in the knowledge graph to find her identifier.

[Tool]
Top 10 entity alternatives:
1. empl Karen Brant@company org (<http://ld.company.org/prod-instances/empl-Karen.Brant%40company.org>): is a Employee
2. empl Sylvester Brant@company org (<http://ld.company.org/prod-instances/empl-Sylvester.Brant%40company.org>): is a Employee

[Assistant]
The search for "Ms. Brant" returned two entities:
1. Karen Brant (likely the correct "Ms. Brant")
2. Sylvester Brant

Since "Ms." typically refers to a female, I will proceed with "Karen Brant" as the entity of interest.

Next, I need to find which property links an employee to their department. I will search for properties related to "department" for the entity "empl-Karen.Brant@company.org".

[Tool]
No property items found

No other items found

[Assistant]
No properties directly related to "department" were found for Karen Brant. It's possible that the property uses a different label or terminology, such as "works in", "member of", "affiliation", or similar.

I'll try searching for properties related to "works" for Karen Brant to see if any relevant properties appear.

[Tool]
No property items found

No other items found

[Assistant] No properties related to "works" were found either. It's possible the property uses another common term such as "member", "affiliation", "organization", or "team". I'll try searching for "member" next.

[Tool]
No property items found

No other items found

[Assistant] Still no relevant properties found. To broaden the search, I'll look for all properties associated with Karen Brant to see if any of them might indicate her department or organizational affiliation.

[Tool] Got no rows and 3 columns

[Assistant]
It appears that there are no triples in the knowledge graph for Karen Brant, meaning there is no information stored about her, including her department.

Given this, I am unable to construct a SPARQL query that would answer the question "In which department is Ms. Brant?" because the necessary data does not exist in the knowledge graph.

I will cancel and explain the situation.

Here is a phone directory of everyone on staff who does not manage anyone, including their name, email, and phone, sorted by name. The name is extracted from the email address in the IRI, as there is no explicit name property.

Give me a phone directory of everyone on staff who does not manage anyone, I need name, email, and phone, sorted by name?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
ck25 at http://localhost:9333

You can use the following SPARQL prefixes implicitly in all functions:

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Give me a phone directory of everyone on staff who does not manage anyone, I need name, email, and phone, sorted by name?

[Assistant]
Let's break down the question:

1. We need a list of all staff members.
2. For each staff member, we need their name, email, and phone.
3. We only want staff who do not manage anyone (i.e., they are not a manager of anyone else).
4. The results should be sorted by name.

Step 1: Identify how "staff" is represented in the knowledge graph. Let's search for "staff" as an entity.

Step 2: Identify properties for name, email, and phone.

Step 3: Identify how "manages" or "manager" relationships are represented.

Let's start by searching for "staff" as an entity.

[Tool] No entity items found

[Assistant] No entity labeled "staff" was found. It's possible that staff members are represented as "Person", "Employee", or similar. Let's try searching for "person" and "employee" as entities to see how staff might be represented.

Top 10 entity alternatives:
1. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent

[Assistant]
We have found two relevant classes:
- foaf:Person
- pv:Employee (which is a subclass of Agent)

Since "Employee" is more specific to staff, let's use pv:Employee as our base class for staff.

Next, let's identify properties for name, email, and phone. We'll search for these properties.

Here's what I have established so far:
- Employees are of type pv:Employee.
- Email and phone are available via pv:email and pv:phone.
- The "has manager" relationship is represented by pv:hasManager, where the subject is the employee and the object is their manager.

However, there is no direct "name" property for employees. The only available identifiers are the IRIs, which encode the name in the format "empl-First.Last@company.org". Since no explicit name property is present, I will extract the name from the IRI using SPARQL string functions.

To get staff who do not manage anyone, I need to select employees who are not the object of any pv:hasManager triple.

Now, I will write a SPARQL query that:
- Selects all employees (?empl) of type pv:Employee.
- For each, gets their email and phone (if available).
- Filters to only those who are not the object of any pv:hasManager triple.
- Extracts the name from the IRI.
- Orders the results by name.

Let's construct and execute this query.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which department have more than 5 employees? I need their names and the number of employees.

[Assistant]
Let's break down the question:

1. We need to identify "departments" in the knowledge graph.
2. For each department, we need to count the number of employees.
3. Only departments with more than 5 employees should be returned.
4. For each such department, we need the department's name and the number of employees.

First, I will search for entities related to "department" to find the correct class or entity.

[Tool]
Top 10 entity alternatives:
1. Department (pv:Department): A department in an organization.
2. emoji department store svg?color=#D6AF00&format=svg (<https://api.iconify.design/arcticons/emoji-department-store.svg?color=%23D6AF00&format=svg>)

[Assistant]
The entity pv:Department represents a department in an organization. Next, I need to determine how employees are related to departments. Typically, there might be a property like "has employee", "member", or "works in".

I'll search for properties related to "employee" to see how employees are associated with departments.

[Tool]
Top 10 property alternatives:
1. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager
2. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
3. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
4. contributor (dct:contributor)
5. created (dct:created)
6. eligible for (pv:eligibleFor): Valid product service combinations (bundles, accessories)., has domain Service, has range Product
7. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
8. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
9. creator (dct:creator)
10. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier

[Assistant]
The property pv:memberOf has the range Department and domain Agent, which likely includes employees. To confirm, I should check if there is a specific Employee class and how it relates to Agent.

I'll search for the "Employee" entity to verify its existence and relationship.

[Tool]
Top 10 entity alternatives:
1. Employee (pv:Employee): An employee in my company., is subclass of Agent
2. employee line svg?color=#D6AF00&format=svg (<https://api.iconify.design/clarity/employee-line.svg?color=%23D6AF00&format=svg>)

[Assistant]
There is a class pv:Employee, which is a subclass of Agent. This confirms that employees are Agents, and the property pv:memberOf can be used to link employees to departments.

Now, I need to:
- Find all departments (pv:Department).
- For each department, count the number of employees (pv:Employee) who are linked via pv:memberOf.
- Filter for departments with more than 5 employees.
- Return the department's IRI, name (label), and the count.

I'll check if departments have a label property (likely rdfs:label or similar) by listing properties of pv:Department.

[Assistant]
pv:Department uses rdfs:label for its name. Now, I will construct a SPARQL query that:

- Finds all departments (?dept) of type pv:Department.
- Counts the number of employees (?emp) of type pv:Employee where ?emp pv:memberOf ?dept.
- Filters for departments with more than 5 employees.
- Optionally returns the department's label.

Here is the query I will use.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Per product category, what's our lightest and heaviest hardware item?

[Assistant]
Let's break down the question:

1. Entities:
   - Product categories
   - Hardware items (likely a subclass or type of product)
2. Properties:
   - Category membership (which product belongs to which category)
   - Weight (to determine lightest and heaviest)
   - Product type (to filter for hardware items)

Step 1: Identify how "hardware item" is represented in the KG. Let's search for "hardware" as an entity.

Step 2: Identify the property for "weight".

Step 3: Identify the property for "category" or "product category".

Let's start by searching for "hardware" as an entity.

[Tool]
Top 10 entity alternatives:
1. Hardware (pv:Hardware): The hardware products produced., is subclass of Product
2. hardware chip outline svg?color=#D6AF00&format=svg (<https://api.iconify.design/ion/hardware-chip-outline.svg?color=%23D6AF00&format=svg>)

[Assistant]
The entity "pv:Hardware" represents hardware products and is a subclass of Product. This is likely the class we need to filter for hardware items.

Next, let's search for the property representing "weight" to find the lightest and heaviest items.

[Tool]
Top 10 property alternatives:
1. weight (g) (pv:weight_g): The weight of an item measured in grams., has domain Hardware
2. quantity (pv:quantity): The quantity needed., has domain BOM Part
3. amount (pv:amount): has domain Price, The amount.
4. height (mm) (pv:height_mm): The height of an item measured in millimeter., has domain Hardware
5. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
6. currency (pv:currency): has domain Price, The currency.
7. type (rdf:type)
8. name (foaf:name):

9. name (pv:name): The name of something.
10. width (mm) (pv:width_mm): The width of an item measured in millimeter., has domain Hardware

[Assistant]
The property "pv:weight_g" represents the weight of an item in grams and has the domain Hardware. This is the property we should use to determine the lightest and heaviest hardware items.

Next, let's search for the property representing "category" or "product category" to group hardware items by their category.

[Tool]
Top 10 property alternatives:
1. has category (pv:hasCategory): The category name of a product., has range Product Category, has domain Product
2. label (rdfs:label)
3. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
4. type (rdf:type)
5. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
6. vocabulary (void:vocabulary)
7. name (foaf:name):

8. name (pv:name): The name of something.
9. sub Class Of (rdfs:subClassOf)
10. is Defined By (rdfs:isDefinedBy)

[Assistant]
The property "pv:hasCategory" represents the category of a product and has the range "Product Category". This is the property we should use to group hardware items by category.

Now, let's summarize our findings:
- Hardware items: instances of pv:Hardware
- Weight: pv:weight_g
- Category: pv:hasCategory

Next, let's check how categories are represented (as entities or literals) by listing some values for pv:hasCategory.

Categories are represented as entities like "prodi:prod-cat-Sensor", "prodi:prod-cat-Crystal", etc. Hardware items have IRIs like "prodi:hw-A145-1240844".

Now, let's check if these hardware items have the property "pv:weight_g" and what the values look like.

[Assistant]
Hardware items have the property "pv:weight_g" with integer values representing their weight in grams.

Now, to answer the question, we need to:
- For each product category, find hardware items in that category.
- For each category, select the hardware item with the minimum and maximum weight.

We should also try to include the category label and optionally the hardware item label for clarity.

Let's check if categories and hardware items have labels (e.g., rdfs:label or pv:name). I'll check for labels on a sample category and hardware item.

[Assistant]
Both categories and hardware items have rdfs:label and pv:name properties. We can use rdfs:label for human-readable output.

Now, let's construct the SPARQL query:
- For each category, find hardware items in that category.
- For each category, select the hardware item with the minimum and maximum weight.
- Return the category IRI and label, the hardware item IRIs and labels, and their weights.

This requires grouping and subqueries for min/max selection. Let's proceed to build the query.

[Tool]
Failed to call function execute:
failed to parse input: parse error at position 656 for token UNDEF with content 'UNDEF' (the input most likely does not follow the grammar)

[Assistant]
The error indicates that the use of UNDEF in BIND is not supported in this SPARQL endpoint. Instead, I need to use a different approach to select the lightest and heaviest hardware items per category.

A common pattern is to use subqueries to select the hardware item(s) with the minimum and maximum weight per category.

Let's proceed step by step:
1. For each category, find the hardware item(s) with the minimum weight.
2. For each category, find the hardware item(s) with the maximum weight.
3. Combine the results.

I'll start by writing a query to get the lightest hardware item per category.

[Assistant]
Both queries work and return the expected results. To provide a complete answer, I will combine both queries into one, using subqueries for the lightest and heaviest hardware items per category, and return the IRIs and labels for categories and hardware items, as well as their weights.

Here is the final SPARQL query.

I could not find any entity in the knowledge graph matching 'SkySync MechWave' or any close variant. Without a matching product entity, I cannot determine which BOM or BOM parts are associated with it, and therefore cannot answer the question about the countries from which its BOM parts are delivered.

From which countries are the BOM parts of our SkySync MechWave delivered?

You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

You can use the following SPARQL prefixes implicitly in all functions:

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] From which countries are the BOM parts of our SkySync MechWave delivered?

[Assistant]
Let's break down the question:

1. "BOM parts" refers to Bill of Materials parts.
2. "SkySync MechWave" is likely a product or assembly.
3. The question asks for the countries from which these BOM parts are delivered.

Step 1: Identify the entity for "SkySync MechWave".
Step 2: Identify how BOM parts are linked to this product.
Step 3: Find the property that links BOM parts to their delivery country.

I'll start by searching for the entity "SkySync MechWave".

[Tool] No entity items found

[Assistant]
The search for "SkySync MechWave" did not return any entities. It's possible that the product is named differently in the knowledge graph, or that it is represented with a slightly different label.

Next, I'll try searching for "SkySync" and "MechWave" separately to see if either term matches an entity in the knowledge graph.

[Tool] No entity items found

[Tool] No entity items found

[Assistant]
Neither "SkySync" nor "MechWave" returned any entities. It's possible that the product is listed under a different name or abbreviation, or that the knowledge graph uses a different naming convention.

To proceed, I'll search for "BOM" or "Bill of Materials" to see if there are any entities or classes related to BOM parts, which might help us identify related products or assemblies.

[Tool]
Top 10 entity alternatives:
1. BOM Part (pv:BomPart): A (number of) part(s) in a BOM.
2. bom 4 (prodi:bom-4): is a Bill of Material (BOM)
3. bom 19 (prodi:bom-19): is a Bill of Material (BOM)
4. bom 12 (prodi:bom-12): is a Bill of Material (BOM)
5. bom 2 (prodi:bom-2): is a Bill of Material (BOM)
6. bom 11 (prodi:bom-11): is a Bill of Material (BOM)
7. bom 18 (prodi:bom-18): is a Bill of Material (BOM)
8. bom 6 (prodi:bom-6): is a Bill of Material (BOM)
9. bom 15 (prodi:bom-15): is a Bill of Material (BOM)
10. bom 5 (prodi:bom-5): is a Bill of Material (BOM)

I have not found any entities matching "SkySync MechWave" or its components in the knowledge graph. However, I did find several BOM entities and a class "BOM Part" (pv:BomPart).

Since the product name is not directly found, I will try to find out if any of the BOMs (e.g., prodi:bom-4, prodi:bom-19, etc.) are associated with a product that could be "SkySync MechWave". I'll list the properties of one of these BOMs to see if there is a link to a product or assembly name.

Despite multiple attempts, I could not find any entity in the knowledge graph that matches "SkySync MechWave" or any close variant. The available BOMs are associated with products like "PulseCraft Vertex", "MechaScape IonDrive", "AeroVibe Matrix", "NexaCore Integrator", and "TransElectro Voyager", but none match the requested product.

Without a matching product entity, I cannot reliably determine which BOM or BOM parts are associated with "SkySync MechWave", and therefore cannot answer the question about the countries from which its BOM parts are delivered.

If you have an alternative product name, spelling, or additional context, please provide it. Otherwise, I must conclude that the required information is not present in the knowledge graph.

I will cancel the attempt and provide an explanation.
