CatMDEdit is a metadata edition tool that facilitates the documentation of resources, with special focus on the description of geographic information resources. The main new feature that this new version includes is a conversion gateway between MARC21 and ISO19115 standards. This conversion gateway is the result of the research carried out in the GTI PC-IDEE (Interdisciplinary Working Group on Cartographic Heritage in the SDI) in the context of the Spanish SDI Working Group (http://www.idee.es/en/web/guest/subgrupos-de-trabajo). The technical specifications of this work can be obtained at http://metadatos.ign.es/metadatos/Patrimonio_cartografico. In addition to this, new adaptations have been added to this version in order to guarantee the INSPIRE Implementation Rules compliance.
