File level is not a meaningful level for curatorial uses… Which DRS files make up my digital manuscript?

Objects Aggregations of files that together
represent a coherent unit of content All the files that make up a single digital book All the master and use copies representing a
single photograph Useful for management, reporting and
searching “How many PDS document objects do I have in
the DRS?”
Objects New hook for metadata
Administrative categories (projects, exhibits, collections, etc.)
Descriptive metadata, catalog records

Content models Object types Define
valid file formats and relationships known delivery and rendering applications associated assessments and preservation plans
Enforce conformity - we know what we have in the DRS and can monitor & preserve it
DRS 2.1 content models – deposit & delivery1. Still image

2. PDS document Page-turned documents, delivered by PDS
3. Document Initially just PDF files, delivered by FDS

New metadata
Object descriptors A METS metadata file per object on the file
system alongside content files Descriptive, administrative, preservation,
technical and structural metadata Describes the object, all its files and bitstreams
and related significant events Gives the metadata the same secure storage
as the content files Self-contained, portable objects
The move to standards PREMIS -- for key preservation metadata,
including Events that affect content Relationships that are not implicit
MODS -- for descriptive metadata Form-specific schemas for technical metadata,
including MIX for images textMD for text DocumentMD for PDF and other document formats More to come…
Supplemented by local administrative schemas
New local metadata adminCategory adminFlag captions, phase 2

Now for objects and files of all types
Tracking changes DRS 2 will keep track of
Changes that affect content Troubleshooting content errors Key administrative metadata
Three types: Events Administrative flags “Versioned” metadata elements
Not tracking every metadata change

Overall schedule
Overall schedule Available now: first release of BatchBuilder
2 for depositor training and testing Supports 5 content models
Fall 2010 – Summer 2011 BatchBuilder 2 enhancements & bug fixes Web Admin 2 development and testing
~September 2011: BatchBuilder 2 and Web Admin 2 in production
BatchBuilder 2
BatchBuilder 2 Will build batches of objects rather than
batches of files Will automatically determine most
technical metadata (using FITS) Will automatically create all object
descriptors (using OTS)
BatchBuilder 1 BatchBuilder 2
Expects files and creates batches of files.
Expects objects and creates batches of objects.
Can use an existing PDS METS file for PDS objects.
Can import a structmap from an “old-style” PDS METS file to create a PDS Document descriptor.
Uses batch genres. Uses DRS Content Models.
Uses a supplied HOLLIS ID to import contents of a HOLLIS record to a PDS METS Label.
Uses a supplied HOLLIS ID to import contents of a HOLLIS record into the MODS section of the object descriptor.
Batch level and directory level metadata entered in Batch Template panel.
Object level and directory level metadata entered in Object Template.
Project level metadata is entered in Administrative Properties panel.
Project level metadata is entered in Deposit Settings panel.
No depositor authorization – anyone with access to the ftp dropbox can load batches.
Depositor authorization – only depositors with permission to load into a particular owner code can load batches into that owner code.
