Schemas at the British Library
The British Library uses the following schema items:
ALTO is a proprietary schema developed by CCS GmbH, a provider of content conversion and digitisation services. Intended for use as a METS extension schema, ALTO is an XML format for storing OCR text and accompanying layout information. This can be used, for example, to relate blocks of text and words to coordinate positions in an image file.
This schema is an extension to version 0.2 of the “NISO Metadata for Images in XML (NISO MIX)” schema. The extension specifically adds constants and enumerations to handle attributes of the JPEG 2000 file type which were not provided in the original schema.
This RDF schema describes properties and classes defined to facilitate the description of bibliographic resources and their relationships to other entities. The properties and classes defined by this schema supplement properties and classes from other ontologies. A diagram of the full model as used by the British Library is available at: http://www.bl.uk/bibliographic/datafree.html
The Process schema is a proprietary schema developed by The British Library. It defines all relevant elements and attributes that are required by the Library's Ingest Workflow Management System.
Qualified Dublin Core (DCQ) application schema Created to permit DCQ in OAI-PMH responses Based almost entirely upon Matthew Mascord's work at http://epubs.cclrc.ac.uk/xsd/qdc.xsd - just changed the targetNamespace and updated the schemaLocation of the include."
