1. Metadata Frameworks
Fall 2003

2. Metadata Frameworks ADN - for online/offline resources **
DLESE-IMS - for online resources
Annotation - resource reviews, comments **
Collection - collection characteristics **
News-Opps - announcements
**Design - Venetian Blind with chameleon namespaces
Overall Challenge - Jan 2004 metadata workshop - whole ball of wax per Mike Mayhew

3. ADN records Web-based resources where resources are:
Modules, lesson plans, activities, etc.
Datasets (remote sensed, in-situ, model)
Guides, text, visuals, imagery, etc.
Strong data-typing with enforced required fields
Has educational, technical, geospatial, temporal, relations, right, cataloger, creator, general categories
Challenge - no direct meta generation support

4. DLESE-IMS records No data-typing; Required metadata not enforced
Same ADN categories just less info in each category
Geospatial and temporal are completely different than ADN (causes problem records for ADN)
Has metadata generation support

5. Annotation records Are the gatekeeper to the Reviewed Collection
Are the gatekeeper as to whether library users can read or contribute reviews
Can exist without ADN records
Only 1 annotation type per record
Annotations are in the record or a URL sends library user to a new site for the annotation
Strong data-typing with enforced required fields
Challenge - no direct meta generation support

6. Collection records (1)
Overall collection characteristics (title, descr.)
Contains DPC collection key and metadata format (how to track collections through DPC)
Indicates how a collection arrives at the DPC
Is the collection OAI harvestable & the OAI info
Is the collection generated at the DPC
Is the collection ed, ftp’ed or what
Moderate data-typing with enforced required metadata

7. Collection records (2)
Indicates if/how collections can be redistributed
Info about item-level catalog record #’s
Indicates super/sub/associated collections
Can indicate ADL buckets for a collection
Captures the additional info needed for NSDL
Tracks accessioning and alignment with DLESE collection policies per requirement of the Collections Accessioning Taskforce

8. Collection records (3)
Challenge - not sure if framework has all needed information
Challenge - to produce valid records requires both DPC staff and a collection builder to create record
Challenge - need to incorporate into other DLESE systems (DDS, histograms, OAI)
Challenge - no metadata generation support

9. News and Opps
Allows for different announcement like grants, conf. wrkshps, interns. and start/stop, post/archive dates (non-standard)
Has metadata generation support
No vocabs or data typing except in GUI
No longer valid records
Mixes presentation with data (html, special chars issues)
Challenge - per Karon, core services involvement; need better discovery and framework revamp?

10. Dependencies and Versioning (1)
All frameworks are independent; even though some have same fields (good or bad???)
All controlled vocabularies are individual schemas so that they can be plugged into any framework (namespaces are hidden)
Collection, ADN & Anno are versioned in CVS

11. Dependencies and Versioning (2)
Collection, ADN & Anno records validate at schema locations on the metadata website through their overarching wrapper schema
Metadata/adn-item/0.6.50/record.xsd
Metadata/collection/0.1.01/collection.xsd
Metadata/annotation/0.1.01/annotation.xsd
New framework versions are issued when
a tag is changed
a vocabulary is changed (add/delete)
or a new or modified field causes a structure change

12. Dependencies and Versioning (3)
Challenge - the schemas enforce *lots* so they have lost some plug-n-play & the records are less flexible in coping with change
Challenge - if give up some enforcement, records are more flexible when changes occur but data is more suspect (this philosophy needs to work closely with a UI because the UI would have to pick up some of the data enforcement)--- Probably not good for ADN but worth high consideration for News & Opps.
