Schema types

The schemas fall into the types below, each with its own way of naming its schemas. The schema browser lists every schema, and the schema files are in the schemas directory on GitHub.

Type	Description	Names
Data Previews and Releases	The catalogs of each Rubin data preview and data release, as served to users.	Start with dp for data previews or dr for data releases, such as dp1.
Science Pipelines	The catalogs produced by the Science Pipelines, which change as the pipelines are developed and are checked against the pipeline outputs in continuous integration.	Named after the instrument or simulation, such as lsstcam, hsc or imsim, with shared definitions in drp_base.
Solar System	Column definitions for the Solar System tables.	Start with sso, such as sso_base.
Alert Production and Prompt Products	The results of nightly alert production and prompt processing.	apdb and ppdb, and several other related schemas.
Consolidated Database	Information about each exposure and visit, from the observatory systems and data processing, with a schema for each instrument (cdb), and the Transformed EFD, which summarizes telemetry from the Engineering and Facilities Database (EFD) over each exposure and visit (efd).	Start with cdb for the Consolidated Database or efd for the Transformed EFD, followed by the instrument, such as cdb_lsstcam.
IVOA standards	Tables following standards of the International Virtual Observatory Alliance (IVOA).	Such as ivoa_obscore and obsloctap.

Note

A schema’s file name is usually the same as the schema’s name, but not always. For example, the IVOA schemas in ivoa_obscore.yaml and obsloctap.yaml are both named ivoa, following the IVOA’s standards.
