TermConnect Developer Reference

For theme developers and plugin authors who integrate with TermConnect via its PHP API, hooks, and REST endpoints.

For end-user configuration and feature guidance, see the User Guide.

This reference is split into the following pages:

• Filters — tc_link_types, tc_term_links_see_also_html, htax_term_uris, htax_term_external_posts, and tc_index_extra_uris.
• Term Links API — the link type registry, per-term link functions, the tc_term_uris_changed action, the database index, and cache management.
• Peer Fetch API — validation, term resolution, post fetching, scoring, and FOAF discovery.
• REST API — the X-TermConnect header, term endpoint fields, and the htax_term_uri query filter.
• Settings Reference — every key in the tc_settings option.
• External Documents — contributing peer-site posts to consumers via HyperTaxonomy’s htax_term_external_posts hub.
