MetaData
the Malete metadata record

overview

Every database may have a metadata record assigned. The system may also have a default metadata record containing defaults.
The core defines metadata fields 001-009, to be used in the same way by all applications and environments.
  • 001 name and options
    as used by the core on the command line
  • 002 unused
    (see TagUse )
  • 003 content-type
    contains a MIME charset and other information mostly for the client for proper interpretation of the data
  • 004 collation
    definition or reference used by the core as detailed in charsets and collation
  • 005 version
    last modified time of this metadata
  • 006 field definition
    as of RecStruct
  • 007 unused (index definition?)
  • 008 unused (references?)
  • 009 unused (stopwords? any?)


We may use an CDS/ISIS compatibility block, e.g. 01x, to store the original contents of files like the .FST or ISISAC.TAB from imported CDS databases for use by some compatibility application.
