CollectiveAccess is a highly configurable cataloguing tool and web-based application for museums, archives and digital collections. Available free of charge under the GPL open-source license, it requires little to no custom programming to support a variety of metadata standards, external data sources and repositories, as well as most popular media formats. In addition to multilingual cataloguing facilities, it allows publication of this data in the languages of your choice.
Current users include representatives from a wide range of fields: fine art, anthropology, film, oral history, local history, architecture, material culture, biodiversity conservation, libraries, corporate archives, digital asset management, and many more. This community of partners has contributed funding, planning and software development resources, resulting in a series of specialist features.
CollectiveAccess can handle a long list of digital media formats, including many popular image, video, audio and document formats. All accepted formats can be automatically re-sized, watermarked and converted to web-viewable formats using criteria you define. Multi-page documents can be conveniently viewed on the web, regardless of original format, using a standards-based page-viewing interface.
