The Metadata Object Description Schema (MODS) is a bibliographic metadata standard implemented in XML. It reimplements a subset of the elements of MARC (Machine Readable Cataloging) using language-based tags instead of numeric ones, and groups them somewhat differently. It is intended both as a simplified version of MARC 21 and as a richer alternative to Dublin Core for applications such as metadata syndication/harvesting and the documentation of digital information packages.
It was developed in 2002 by the Library of Congress Network Development and MARC Standards Office along with a group of interested experts.
Digital Repository of Ireland (DRI) is a national trusted digital repository (TDR) for Ireland’s social and cultural data. The Repository supports records catalogued in four different metadata standards: Dublin Core, EAD, MARC XML and MODS.
