11. Difference between Museum and Library Full Darwin code has parallels in MARC Many more commercial and custom products Larger installed base Library Entries somewhat more detailed There is a MARC(XML) and MARC Lite MARC differentiates among material types

12. Digital Content Transport METS – Metadata Encoding and Transmission Standard The METS schema is a standard for encoding descriptive, administrative, and structural metadata regarding objects within a digital library, expressed using the XML schema language.

14. METS Components METS Header Descriptive Metadata Administrative Metadata File Section - The file section lists all files containing content which comprise the electronic versions of the digital object. elements may be grouped within elements, to provide for subdividing the files by object version.

15. I/O Submission Information Package (SIP), which is sent from the information producer to the archive; the Archive Information Package (AIP), which is the information package actually stored by the archive; and the Dissemination Information Package (DIP), which is the information package transferred from the archive in response to a request by a consumer.

17. Open Archives Initiative Protocol for Metadata Harvesting The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a low- barrier mechanism for repository interoperability. Data Providers are repositories that expose structured metadata via OAI-PMH. Service Providers then make OAI-PMH service requests to harvest that metadata. OAI-PMH is a set of six verbs or services that are invoked within HTTP.

We present a framework that separates digital object experience, or rendering, from digital object storage and manipulation, so the rendering can be tailored to particular communities of users.
