Tool for cataloging and locating environmental resources on the web
MDweb is an open source generic tool designed for such distributed collaborative work. It provides a web service to catalog, and help others locate resources, documents, and services for geographic or non-spatial information. MDweb is based on international geographic-information standards for metadata and communications.
MDweb focuses on the spatial and semantic aspects in resource description, and searches by using thematic and spatial reference bases specific to the target application. MDweb also includes extensive features to automate data entry and manage referential bases such as providing editing templates, building spatial databases and accessing thesauruses.
