Technology Standards and Specifications

TL;DR: WoT hosts ~25 technology-standards taxonomies that don't fit cleanly into the industry / regulatory / academic / financial buckets but still describe stable enumerated value spaces: telecom and networking specs (3GPP, ITU-T, ITU-R, IETF RFC, IEEE), connectivity (Bluetooth, USB, PCI-SIG, JEDEC, SEMI, VESA), web/internet (MIME types, HTTP status codes, SPDX licenses), cybersecurity catalogs (MITRE ATT&CK, CVE types, OWASP Top 10), AI / cloud-native taxonomies (AI Model Types, Cloud Native Landscape), and supplementary engineering / scientific reference (SI Units, Container ISO 6346, Periodic Table grouping is in environmental). Plus a handful of regulatory administrative anchors that don't belong in regulatory-standards.md (CFR Titles, USC Titles, IRS Forms, VAT Rate Types).

Telecom and networking standards

System	Codes	Authority	Scope
`3gpp_specs`	18	3GPP	3GPP technical specifications (cellular, 5G, etc.)
`itu_t`	19	ITU-T	International Telecommunication Union telecom recommendations
`itu_r_bands`	16	ITU-R	ITU-R radio frequency band designations
`ietf_rfc`	15	IETF	IETF RFC categorical groupings

Why this is a "miscellaneous" page

The systems above are real, published, stable, and within size cap (per the Inclusion Policy) - so they belong in WoT - but they don't form a coherent topical cluster that justifies a dedicated page on its own. Putting them here keeps them findable while honoring the Karpathy four-channel pattern: catalog row plus topical context plus llms-full.txt presence plus wiki API exposure.

If your downstream product cares about a specific subset (say, telecom standards or cybersecurity catalogs), filter by system_id prefix at the API:

GET /api/v1/systems?prefix=itu_
GET /api/v1/systems?prefix=mitre_
