Tables defined within this resource descriptor

dc.metastore
A table for storing all kinds of key-value pairs. Key starting with an underscore are for use by user RDs.

Only one pair per key is supported, newer keys overwrite older ones.

Currently, this is only used for schemaversion, the version of the DaCHS system tables as used by gavo upgrade to figure out what to change. gavo upgrade manages this.

From your code, you can use base.getDBMeta(key) and base.setDBMeta(connection, key, value) to put persistent, string-valued metadata in here; if you use this, would you tell us your use case?
dc.tablemeta
A table mapping table names and schemas to the resource descriptors they come from and whether they are open to ADQL queries.

This is used wherever DaCHS needs to go from a database name to the resource description, e.g., when generating tableinfo.

The table is maintained through gavo imp; to force things out of here, there's gavo drop (for RDs; use -f if the RD is gone or meoved away) or gavo purge (for single tables).
