I. Options for Addressing Finding Aid Discovery,
Retrieval & Integration at Columbia
The current availability of MARC cataloging data for the Greene
& Greene and Digital Aviador projects, along with functionality
now available via CU Master Metadata File, suggest a practical solution
to some of the issues & problems raised by the creation of archival
finding aids at Columbia (see brief discussion of these issues in
section II below).
By implementing what could be called "Index Records"
either in CLIO or in the MMF and linking them to finding aids--either
at the document level or directly to specific sections in a finding
aid (identified with "targets" or "anchors")--
we could retain flexible and sustainable access to finding aid information
as well as functional integration of finding aids within the larger
electronic resource environment.
A summary description of this approach follows:
- finding aids would be "cataloged" in CLIO, using an
index (or "access") level record rather than a standard
descriptive catalog record; in some cases a finding aid would
have only a single catalog record; in others there would be 'analytic'
records for series or subseries within the finding aid;
- the "index record" would contain all necessary normalized
name, subject and other headings, created according to standard
cataloging practices;
- each "index record" would have a single link to the
corresponding finding aid or to a location within the finding
aid;
- "index records" would be loaded into the MMF, where
image links would be created and maintained. (NB: The master
record for finding aid catalog records would in this case be CLIO,
while the master listing of image or other digital object links
would be the MMF.)
- finding aids would carry one or more internal "targets"
or "anchors" which could be used for linking from CLIO
or Web pages back to the finding aid;
- image (etc.) descriptive and structural metadata would be entered
into the MMF for all images related to a finding aid (or similar
digitization project), and the image stored according to guidelines
(to be) established for CU's digital image repository;
- image links would also be incorporated as appropriate directly
into the finding aids, but these would be pointers to the descriptive
& structural metadata stored in the MMF;
- the MMF would be used to generate project and other types of
Web listings and displays based on the access points in "index
records"; these Web listings and displays could point users
either to the finding aid or, if needed, directly to the images
themselves;
- for projects other than G&G and Digital Aviador--where standard
cataloging was already completed--finding aids would be given
new index-level cataloging in CLIO (or possibly directly in the
MMF depending on the nature of the project).
Other issues mentioned in section I.B. below relating to management
of finding aids themselves will also need to be addressed. The
proposed strategy, however, un-links the problems of finding aid creation
and maintenance from those of metadata maintenance, image management
and campus-wide integration of eresources.
II. Issues in integrating archival finding aids into
Columbia's metadata environment
A. Discovery, Retrieval, Integration
Effective 'discovery' and retrieval of information in finding aids
may be difficult at Columbia because we currently lack:
- a technical infrastructure for indexing or searching individual
finding aids or images linked to finding aids other than standard
keyword indexing
- a strategy for cross-document searching of multiple finding
aids
- a mechanism to integrate indexing or searching of findings aids
with related materials not usually described in finding aids,
e.g., material cataloged in the online catalog, local & remote
online text archives, other digital library project data
B. Data Maintenance & Technology Migration
Maintenance of finding aid information is currently difficult because:
- normalized access terms embedded in archival finding aids (e.g.,
names and subjects) cannot readily be updated or managed with
existing bibliographic or other tools
- there is currently no single repository of archival finding
aids at Columbia which would allow for effective management of
the components (such as DTDs, CSS stylesheets, XLS stylesheets,
various entity and rules files, etc.) necessary to support the
current EAD/SGML apparatus or the necessary migration to XML,
XLink, XML schemas, etc.
- there is currently no implementation of a standard "digital
object lookup" or URN scheme at Columbia that would allow
incorporating persistent links to images or other external resources
into finding aid documents
