The Unified Astronomy Thesaurus (UAT) provides a comprehensive,
interlinked set of concepts relevant for astronomy and astrophysics using
SKOS. It is taken up in the Virtual Observatory at least for registry
subject keywords. For various reasons, it is desirable to have the UAT
available subject to the constraints laid down in the IVOA Vocabularies
in the VO 2 specification. This Note describes the rationale and the
details of the UAT adoption by the IVOA.
Query service for observation metadata for all CADC archival data holdings. This service

JCMT, NEOSSAT, OMM, TESS, VLASS.
The current static collections include: APASS, BLAST, CFHTTERAPIX, CFHTWIRWOLF,
CGPS, DAOPLATES, FUSE, HSTHLA, IRIS, MACHO, MOST, NGVS, UKIRT, VGPS.
The curent external collections (metadata only, data served by original data centre) include:
CHANDRA, NOAO, SDSS, SUBARU, XMM.
YouCat is a query service for catalogues hosted by CANFAR. This service
provides Table Access Protocol (TAP) API access to catalogues created by
project teams.
YouCat also implements a prototype VOSI-tables extension that allows users
to create, update table metadata add table content (rows), create indices,
and delete tables in the database. Users can also control access to their
own tables (public to allow anonymous querying, protected so only members
of specified groups can query, and private where only the owner can query).
Users who want to create tables must request an allocation (schema) by email
to support@canfar.net.
Currently available catalogues include: VLASS, CFHTLS, KiDS, PAndAS, RCSLens.
