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.
