Fedora Search Interface Fedora ‘out of the box’ does not come with a web or user interface… It does have a simple search interface however, enabling searching and browsing of the Fedora repository:

Fedora Search Interface searching (Fedora System Metadata) Upon ingest, metadata from the Dublin Core metadata datastream and the Fedora System Metadata is indexed in a relational database and can be searched using the Fedora Search Interface. Fedora System Metadata is administrative metadata, with elements pid, label, fType, cModel, state, ownerId, cDate, mDate, dcmDate, bDef, bMech. For eg., pid~lse:20* retrieves all objects with PID matching the string lse:20 (101 objects in this case):

Fedora Search Interface searching (DC metadata) When DC metadata is not provided, Fedora creates a simple DC datastream, consisting of the dc:title and dc:identifier elements. Otherwise, all 15 basic DC elements can be searched using the Fedora Search Interface (title, creator, subject, description, publisher, contributor, date, type, format, identifier, source, language, relation, coverate, rights). For eg.: symbolism retrieves all objects with the word symbolism in any one of the DC elements (9 objects in this case):

Fedora Search Interface accessing the Object Profile The PIDs (persistent identifier) of the objects returned by the search are hyperlinked and invoke the Object Profile, with links to the Dissemination Index and Item Index for the object:

What’s in Fedora? CLT media database objects: The Centre for Learning Technology (CLT) developed the CLT media database in order to store and manage some of the video and audio content it had digitised for teaching and learning purposes. This content comprises mostly digitised lectures and television programmes (ERA License). The 705 objects in this collection were ingested to Fedora using METS as content packaging tool for the creation of Submission Information Packages (SIPs).The resulting Fedora objects (lse:2000 to lse:2705) include Dublin Core metadata, facilitating discovery via the Fedora Search Interface, CLT metadata (mapped to DC), and the audio or video files (Quicktime, Real Media, Windows Media). Malinowski photographs: The LSE Archives hold a substantial collection of material relating to the anthropologist Bronislaw Kasper Malinowski, including a large collections of photographs from his fieldwork to the Trobriand Islands ( ). These photographs were digitised in recent years. Part of this collection has now been ingested to Fedora (lse:2721 to lse:2772) using METS as content packaging tool. The resulting objects include EAD metadata, the JPEG and TIFF images, and Fedora’s default DC.
