note: >-
  Entity-relationship graph for the GRIN Therapeutics Content API, derived from the OpenAPI component
  schemas, the id-reference fields on each resource, and the `_links` relations observed on live
  responses. Ids are bare integers — this API uses no prefixed or typed identifiers, and post, page
  and attachment ids share a single sequence because WordPress stores all three in one table, so an
  id alone does not identify its type.
identifiers:
  scheme: integer
  shared_sequence: true
  detail: >-
    post, page and attachment ids are drawn from one sequence. Observed values: pages 6-13039, media
    up to 12501, users 5. Term ids (categories, tags) are a separate sequence.
entities:
- name: Page
  rest_base: pages
  operations: [listPages, getPage]
  population: 10
  hierarchical: true
  description: >-
    The substantive content of the site. The ten published pages are Home (11), News (6), Careers
    (9554), Working with Grin Therapeutics / contact (5750), Privacy Policy (9935), About GRIN
    Therapeutics (11950), Our Science (11956), Disease State (11958), Resources for patients and
    caregivers (11960) and Cookie Policy (13039).
- name: Post
  rest_base: posts
  operations: [listPosts, getPost]
  population: 0
  description: >-
    Registered and reachable but empty. GRIN Therapeutics' news items and corporate events are
    authored inside the News page (id 6) rather than as posts, so there is no per-press-release
    resource, no dated archive and no populated feed.
- name: MediaItem
  rest_base: media
  operations: [listMedia, getMediaItem]
  population: 174
  description: >-
    The media library — scientific figures (e.g. NMDA_Receptor_Scaled.png), corporate imagery and
    logos. This is the richest addressable collection on the API.
- name: Term
  rest_base: categories, tags
  operations: [listCategories, getCategory, listTags, getTag]
  description: >-
    WordPress core taxonomy terms. Present but unused — every term returns count 0 because there are
    no posts. Category terms observed include Business; tag terms observed include Creative. These
    are theme defaults, not GRIN Therapeutics' editorial taxonomy.
- name: User
  rest_base: users
  operations: [listUsers, getUser]
  description: Public author records. Agency accounts rather than named GRIN Therapeutics staff (e.g. cglife, bencrossroad-us).
- name: PostType
  rest_base: types
  operations: [listTypes, getType]
  description: >-
    Registry of registered post types — post, page, attachment, nav_menu_item, wp_block,
    wp_template, wp_template_part, wp_global_styles, wp_navigation, wp_font_family, wp_font_face. No
    custom post type is registered, which is why the press releases have no home.
- name: Taxonomy
  rest_base: taxonomies
  operations: [listTaxonomies]
  description: Registry of registered taxonomies — category and post_tag only.
- name: SearchResult
  rest_base: search
  operations: [searchContent]
  description: A projection, not a stored entity — {id, title, url, type, subtype} pointing back at a Page or Post.

traversal:
  mechanism: _links
  description: >-
    Every resource carries a `_links` object with self, collection, about, author, wp:attachment,
    wp:term and curies relations, so the graph above is walkable at runtime without hard-coding
    routes. Passing `_embed` inlines the linked author, featured media and terms under `_embedded`.
