Metadata filters

Metadata filters are routines with which LIBSAFE can process a metadata file and integrate its information into the object cataloging system. Filters can be from processes for the application of XML transformation sheets to complex processes that will check the correct formation and process information about the object (like, for example, the process of a METS containing metadata to be absorbed, but also information about the structure of the object that needs to be contrasted).

Metadata filters in a standard LIBSAFE installation include:

• Empty Metadata Filter. It does not add any metadata information to the catalog. The metadata filter selection being mandatory, this filter solves the situation if we do not wish to import metadata or if we do not have any metadata associated to the preserved objects.

• Simple Metadata Filter. It allows for importing metadata from any XML to any metadata schema, by using XSLT transformation sheets.

• Marc21 METS metadata filter. It is a filter to import standard Marc21 METS.

• Object Name Metadata Filter. It imports the object name as a descriptor. This descriptor will be the only one included in the metadata schema.

• Marc21 METS Droid metadata filter.

• Simple metadata filter plus object name.

• EAD3 METS metadata filter.
