A solution for cataloging geospatial metadata and a web search interface for a corporative collection of datasets has been designed and implemented as a web service.

The tool (CaMM) is a Win32 application that fills a database designed to be compliant with the schema and core elements of ISO 19115 and, in addition, to include extended information (the model used by MiraMon Metadata and Database Relationships Manager, GeMM) like remote sensing parameters, hierarchical keywords and the alphanumeric database description.

CaMM features:

• Digital catalog creation in several database formats using ODBC: MS Access, ORACLE, etc.
• Automatic discovery of geospatial data from several data sources; it doesn't require to insert layer metadata one by one.
• Automatic creation of catalogs.
• Total or partial update of catalogs.
• Preparation of metadata export documents in XML and HTML format following the standard ISO 19115 or others.
• Generation of several catalogs for different types of users.

• Searching different metadata elements with different operators depending on the element type. It also searches by geographical area and by metadata elements with hierarchy: for example, a search with the keyword biology also finds metadata containing botany, zoology, ecology, etc.
• Making sensitive/insensitive searches to stressed words or capital letters.
• The result of the query is a list of metadata brief that can be personalized with different visualization contents and styles. Accessing additional metadata information in other documents as XML, HTML as well as in GeMM application.
• Single click visualization of layers through the MiraMon GIS.
