Museums and the Online Archive of California (MOAC) builds on existing standards and their implementation guidelines provided by the Online Archive of California (OAC) and its parent organization, the California Digital Library (CDL). Setting project standards for MOAC consisted of interpreting existing OAC/CDL documents and adapting them to the projects specific needs, while at the same time maintaining compliance with OAC/CDL guidelines. The present overview over the MOAC technical standards references both the OAC/CDL umbrella document and the MOAC implementation / adaptation document at the beginning of each section, as well as related resources which provide more detail on project specifications.
Critical Arguements
CA The project implements specifications for digital image production, as well as three interlocking file exchange formats for delivering collections, digital images and their respective metadata. Encoded Archival Description (EAD) XML describes the hierarchy of a collection down to the item-level and traditionally serves for discovering both the collection and the individual items within it. For viewing multiple images associated with a single object record, MOAC utilizes Making of America 2 (MOA2) XML. MOA2 makes the images representing an item available to the viewer through a navigable table of contents; the display mimics the behavior of the analog item by e.g. allowing end-users to browse through the pages of an artist's book. Through the further extension of MOA2 with Text Encoding Initiative (TEI) Lite XML, not only does every single page of the book display in its correct order, but a transcription of its textual content also accompanies the digital images.
Conclusions
RQ "These two instances of fairly significant changes in the project's specifications may serve as a gentle reminder that despite its solid foundation in standards, the MOAC information architecture will continue to face the challenge of an ever-changing technical environment."
