# Common Attributes

Each response from the API include some standard attributes for metadata and pagination (for collections) which follow the <code class="expression">space.vars.ionos\_cloud</code> API standards. Most of these will be omitted from the response examples for brevity.

## Type, ID and Pagination in collections

```json
{
  "_links": {
    "next": "https://link-to-next-collection-page",
    "previous": "https://link-to-previous-collection-page",
    "self": "https://link-to-this-collection-page"
  },
  "href": "http://link-to-this-collection-page",
  "id": "UUID-for-this-collection-page",
  "items": [
    ...
  ],
  "limit": 100,
  "offset": 0,
  "type": "collection"
}
```

## Type, ID and Metadata for resources

```json
{
  "href": "https://link-to-this-resource-page",
  "id": "UUID-for-this-resource-page",
  "metadata": {
    "createdBy": "URN-of-creator",
    "createdByUserId": "UUID-of-creator",
    "createdDate": "creation-timestamp",
    "lastModifiedBy": "URN-of-actor",
    "latModifiedByUserId": "UUID-of-actor",
    "lastModifiedDate": "modification-timestamp",
    "resourceURN": "URN-for-this-resource"
  },
  "properties": {
    ...
  },
  "type": "user-or-database"
}
```

If a resource is:

* not created via the API, its `createdBy` field ends with `_unmanaged_`.
* a read-only system resource, its `createdBy` field ends with `_system_`.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.ionos.com/cloud/databases/postgresql/api/v1-api/users-and-databases/common-attributes.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
