  registration and sample payloads observed at https://arbor.bio/wp-json on 2026-07-31
note: >-
  Entity graph of the WordPress content model as this site actually exposes it. Relationships
  were derived from id-reference fields present in real responses (author, categories, tags,
  featured_media, parent, post) and from /wp/v2/taxonomies and /wp/v2/types — not from a
  published object reference, because Arbor publishes none.
id_scheme:
  type: integer
  prefixed: false
  detail: >-
    Bare auto-increment integers, unique within a post type or taxonomy rather than globally.
    An id alone does not identify its entity — always carry the collection with it. Posts and
    attachments share the WordPress posts table, so their ids are drawn from one sequence,
    but a page id will still 404 against /wp/v2/media.
entities:
- name: Post
  route: /wp/v2/posts

  count_observed: 59
  date_range_observed: 2018 to 2026-06-25
  description: >-
    Arbor's press releases and company announcements — financings, partnership news
    (Chiesi, Vertex, Allogene, Samsung Life Science Fund), regulatory designations for
    ABO-101, conference presentations (ASGCT) and executive appointments. This is the
    substantive machine-readable content on the site.
  key_fields: [id, date, date_gmt, modified, modified_gmt, slug, status, link, title, content,
    excerpt, author, featured_media, categories, tags, format, sticky, meta, acf, class_list,
    yoast_head, yoast_head_json, _links]
  relationships:
  - {type: belongs_to, target: User, via: author, note: resolves to an id only; /wp/v2/users is 401 anonymously}
  - {type: has_one, target: Media, via: featured_media}
  - {type: has_many, target: Category, via: categories}
  - {type: has_many, target: Tag, via: tags, note: always empty on this site}

  relationships:

  - {type: has_one, target: Media, via: featured_media}
  - {type: belongs_to, target: Page, via: parent, note: all 11 pages are top level (parent 0) in the REST view, even though the site menu nests them}
- name: Media
  route: /wp/v2/media
  operations: [listMedia, getMedia]
  count_observed: 4
  count_reported: 394
  description: >-
    The media library — logos, leadership headshots, pipeline graphics and press assets.
    X-WP-Total reports 394 items but anonymous callers are returned only 4; the remainder is
    restricted. Direct file URLs under /wp-content/uploads/ remain publicly fetchable and are
    explicitly Allowed in robots.txt.
  key_fields: [id, date, slug, link, title, author, media_type, mime_type, source_url,
    media_details, alt_text, caption, post, _links]
  relationships:

  route: /wp/v2/categories
  operations: [listCategories, getCategory]
  count_observed: 11
  taxonomy: category
  hierarchical: true
  description: >-
    The only classification in active use. One content category, `press-release` (57 posts),
    plus per-year archive categories 2018-2026 and an empty `uncategorized`.
  key_fields: [id, count, description, link, name, slug, taxonomy, parent, meta, _links]

- name: ContactForm
  route: /wp/v2/wpcf7_contact_form
  operations: [listContactForms, getContactForm]
  count_observed: 1
  description: >-
    Contact Form 7 form definition backing the /get-in-touch/ page, exposed as a custom post
    type. Read-only metadata — this route does not submit the form.
  relationships: []
- name: User
  route: /wp/v2/users
  operations: []
  count_observed: null
  description: >-
    Not exposed. Anonymous callers receive 401 rest_user_cannot_view, so author ids appearing
    on posts and pages cannot be resolved to names. Excluded from the OpenAPI.
- name: Comment
  route: /wp/v2/comments
  operations: []
  count_observed: 0
  description: >-
    Permanently disabled — 403 rest_comment_disabled. Excluded from the OpenAPI.

  operations: [listTypes, getType]
  description: >-
    15 registered post types, of which only post, page, attachment and wpcf7_contact_form
    are anonymously readable. The rest (nav_menu_item, wp_block, wp_template,
    wp_template_part, wp_global_styles, wp_navigation, wp_font_family, wp_font_face, popup,
    popup_theme, pum_cta) are editor and plugin constructs.
- name: Taxonomy
  route: /wp/v2/taxonomies
  operations: [listTaxonomies, getTaxonomy]
  description: Registered taxonomies (category, post_tag and editor taxonomies) and the post types they apply to.
- name: Status
  route: /wp/v2/statuses
  operations: [listStatuses, getStatus]
  description: Registered post statuses. Only `publish` is exposed anonymously.
- name: SearchResult
  route: /wp/v2/search
  operations: [searchContent]
  count_observed: 60
  description: >-
    A projection, not a stored entity — a lightweight hit (id, title, url, type, subtype)
    across all searchable content, with an embeddable _links.self to the full object.
relationship_traversal:
  mechanism: _links + _embed
  detail: >-
    Every object carries a _links map (self, collection, about, author, wp:featuredmedia,
    wp:attachment, wp:term, replies). Appending _embed to a request inlines those linked
    objects under _embedded, resolving author, featured media and terms in a single round
    trip instead of one call per relationship. The author relation will not resolve for
    anonymous callers.
