Metadata Object Description Schema (MODS)
"The Library of Congress' Network Development and MARC Standards Office, with interested experts, has developed the Metadata Object Description Schema (MODS), which is a bibliographic element set that may be used for a variety of purposes, particularly for library applications. Information about MODS and the schema (version 1.2) is available
As an XML schema it is intended to be able to carry selected data from existing MARC 21 records as well as to enable the creation of original resource description records. It includes a subset of MARC fields and uses language-based tags rather than numeric ones, in some cases regrouping elements from the MARC 21 bibliographic format. The elements inherit MARC semantics, so are more compatible with existing library data than other metadata schemes.
MODS could potentially be used as follows:
MODS includes a subset of data from the MARC 21 Format for Bibliographic Data. As an element set that allows for the representation of data already in MARC-based systems, it is intended to allow for the conversion of core fields from a MARC 21 record, while some specific data may be dropped. As an element set for original resource description, it allows for a simple record to be created, in some cases using more general tags than those available in the MARC record. The Library of Congress has developed transformations to move MARC 21 records from 2709 form to MARCXML to MODS, with the software available from the MARCXML Web site.
There has been wide review and input to the development of the schema, which is now available for trial use. It will remain stable for the next six months, during which we invite comments as a result of experimentation.

This is very much like MARC in XML with name tags rather than numeric.
