W3C

W3c List Ecosystems

List W3C ecosystems — high-level groupings of related standards efforts. Call without arguments to see all 9 ecosystems. Pass an ecosystem shortname to see which Working Groups and Community Groups belong to it. Useful for mapping the landscape of related groups across a domain.

W3c List Group Chairs

List the chairs (leaders) of a W3C group. Returns chair names. Use this to identify who leads a group before engaging or contributing.

W3c List Group Charters

List all charters for a W3C Working Group or Interest Group. A charter defines the group's scope, deliverables, and timeline. Returns start/end dates, charter URI, patent policy, and any extensions. Use this to understand what a group is committed to delivering and whether a topic is in scope. Only works for WGs and IGs.

W3c List Group Orgs

List organizations and individuals participating in a W3C group. Shows which companies (Google, Microsoft, Apple, etc.) and independent contributors are involved. Returns org/individual name and whether they are an invited expert. Critical for understanding who has influence in a standards effort.

W3c List Group Participants

List participants (members) of a W3C group. Returns names and total count. Useful for gauging group size and activity level, and finding who's involved in a particular standards effort.

W3c List Groups

List W3C groups (Working Groups, Community Groups, Interest Groups, etc.). Filter by group type to narrow results. Returns group name, shortname, type, and creation date. For keyword search across group names and descriptions, use group search instead of listing.

W3c List Group Specifications

List all specifications produced by a W3C group. Requires the numeric group ID from a group detail lookup. Returns specification titles and shortnames. Look up the group by type and shortname first to obtain the group_id.

W3c List Specs By Status

List W3C specifications filtered by their current status. Shows all specs at a given maturity level. Common statuses: 'Working Draft' (~330 specs), 'Candidate Recommendation Draft' (~59 specs), 'Recommendation' (~361 specs). Returns spec titles, shortnames, and links.

W3c List Spec Versions

List all published versions of a W3C specification (newest first). Returns version date, status (Working Draft, Candidate Recommendation, etc.), URI, and rec-track flag. Use this to track spec progression. To get editors of a specific version, use the spec version detail lookup.

W3c Search Groups

Search W3C groups by keyword. Filters by name, shortname, and description. Returns matching groups sorted by relevance (name matches first). Use created_after='2025-01-01' to find recently formed groups. Use active_only=true (default) to exclude closed groups.

W3c Search Specifications

Search for W3C specifications. Two modes: (1) by shortname prefix (fast, direct API) — e.g. shortname='webnn' finds the Web Neural Network API; (2) by keyword in title/description (slower, scans all ~1700 specs) — e.g. keyword='neural network' finds specs you wouldn't find by shortname alone. Use shortname when you know it, keyword when exploring a topic.

W3c Topic Landscape

Get a complete landscape view of a topic at W3C in a single call. Returns all matching groups enriched with participant counts, chairs, spec counts and spec statuses, and related specifications — sorted by participant count (largest/most active first). Eliminates the need for multiple sequential calls to search, get_group, list_specs, etc. Use this as the first tool when researching any W3C topic.
