What is the Hughes Collection?and why are we digitizing it?
http://aok.lib.umbc.edu/specoll/hughes_slideshow.php
• Value: Informational, Evidential & Artifactual
• Uniqueness of the materials
• Significance of the collection & Potential Use
• Access & Enhancements
• Other similar collections online?
• Preservation
• Copyright
• Funding
Selection of Materials to Digitizecommon criteria to consider
How Hughes fits within criteriabesides being a genuinely cool collection…
• Share expertise
• Expand expertise
• Divide Labor
• Fosters creativity
• Shared sense of ownership/pride – a Library-wide, core function
• Ability to work with diverse groups
Collaborating with BMSbenefits of partnerships within the Library
How does this collaboration work?…at least how the Special Collections contribution works…
SC sets up collection in CONTENTdm
(one-time only)
SC determines admin/tech/preserv
metadata fields, creates defaults for
some, populates some during scanning
SC scans glass negatives and fills in
preliminary metadata
SC performs QC on scans
SC saves master files to server
SC uploads images and metadata to
CONTENTdm
BMS takes over – distributing sets of images to describe, applying descriptive metadata, etc. Sometimes comes back to SC to fix problems.
SC composes contextual information, works w/Web Librarian to put on Web, and publicizes the collection

METADATAmore than just descriptive
Types of Metadata
• From NISO Understanding Metadata:• Administrative metadata provides information to
help manage a resource, such as when and how it was created, file type and other technical information, and who can access it.
− Rights management metadata, which deals with intellectual property rights,
− Preservation metadata, which contains information needed to archive and preserve a resource.

Technical Metadataand it can get very technical
NISO Z39.87-2006• Basic Digital Object Info
o Re: file format & compression• Basic Image Info
o Technical info about the digital image• Image Capture Metadata
o Technical info re: image capture including re: scanner, computer, and software used
• Image Assessment Metadatao Technical description of appearance of image during
capture (e.g. target information)• Change History
o Documents edits/processing done to image after captureo Info re: metadata associated with previous versions of
image
Accession No.
TIFF (no compression)
In MB or GB
Grayscale, RGB, CMYK?

Preservation Metadatathis can get tricky
• Currently, this is our standard rights statement:
“This item may be protected under Title 17 of the U.S. Copyright Law. It is made available by UMBC for non-commercial research and education. For permission to publish or reproduce, please see http://aok.lib.umbc.edu/specoll/repro.php or contact Special Collections at speccoll(at)umbc.edu.”
Rights Metadatahow the files can be used
• Rights Metadata• Harvard libraries only express rights in simple, single metadata elements at this time. However, there are
several rights expression languages (RELs) and other rights standards that will be valuable resources for Harvard in the future.
• copyrightMDCopyrightMD is an XML schema for recording characteristics that, taken together, help determine the copyright status of a resource.M
• Creative CommonsCreative Commons provides a range of standardized digital licenses that can be associated with or embedded in open access web resources.
• METSRightsMETSRights is an XML schema for documenting minimal administrative metadata about the intellectual rights associated with a digital object or its parts. METSRights is most often used to record statements to be viewed by professionals managing the content or to be displayed to end users viewing the content. It is not designed to be machine-actionable.
• ONIX For Publications Licenses "ONIX-PL is an XML format for the communication of license terms in a structured and substantially encoded form."
• Open Digital Rights LanguageODRL is an open standard defining a model and vocabulary for the expression of terms and conditions over assets.
• XrMLXrML is a proprietary method for securely specifying and managing rights and conditions associated with all kinds of resources including digital content as well as services. It underlies commercial Digital Rights Management applications. XrML has come to agreements with MPEG and other initiatives to enable them to use XrML as a basis for more specific rights language specifications, such as MPEG21-Part 5: Rights Expression Language.

Quality Controllessons learned?
• QC more ofteno Some images were backward, due to scanner problem or digital file creator error (not too many, but still created more work)
• If you have to re-upload, don’t forget to reindex!
