1. EAD 101: An Introduction to Encoded Archival Description XML and the Encoded Archival Description: Providing Access to Collections Oregon Library Association Eugene, Oregon April 16, 2004 Elizabeth Nielsen, Senior Staff Archivist Oregon State University Libraries http://osulibrary.oregonstate.edu

2. Overview Background on the description of archival materials. The nuts and bolts of EAD including examples of elements and attributes. Why is EAD (in addition to MARC) important to archivists? Demonstrate the NWDA finding aids database.

3. Why? Inform potential users/patrons about collections -- especially important for archival collections which are not “browsable” and with which most patrons are not familiar. Enhance access/use of collections by providing more detailed information. Improve reference assistance.

4. Principles for Description of Archival Materials Different materials best served by different types/levels of description. Collection-level. Hierarchical. Item-level description only for certain materials (e.g. photographs).

5. What’s a Finding Aid? Document that describes an archives collection. Two parts: –Collection-level information. –Inventory or container list at folder- (or item-) level.

6. What Form Now? Usually created initially as word processing files. Posted on the web as HTML files. MARC records created and posted to local OPAC (OASIS), Summit (Orbis Cascades Alliance), and OCLC.

15. Limitations to HTML and MARC Only “full text” searching of HTML finding aids. MARC records have to be created “by hand” from finding aid. Lack of consistency in format and content.

16. What is EAD? Encoded Archival Description

17. EAD is … A set of rules for designating the intellectual and physical parts of archival finding aids so that the information can be searched, retrieved, displayed and exchanged in a predictable, platform-independent manner.

18. EAD Rules Written in the form of an SGML (or XML) Document Type Definition (DTD). The DTD mandates which elements are mandatory for a “valid” EAD document; which attributes are mandatory; and the order for elements and attributes. DTD is NOT a content standard. DTDs are read by computers … humans prefer the Tag Library

19. EAD development Development began in early 1990s. Version 1 of the DTD released in 1998. Version 2002 released in late 2002.

20. Tag Library and Application Guidelines Computers read DTDs … Humans prefer Tag Library and additional guidance. Standard maintained by the Library of Congress Network Development and MARC Standards Office. Tag Library and Application Guidelines published by Society of American Archivists (SAA).

23. Best Practice Guidelines Online Archive of California Research Libraries Group Northwest Digital Archives

24. Role of BPG Ensure uniformity in structure and encoding of finding aids. Promote interoperability within the NWDA database among finding aids from diverse repositories.

27. 3 high-level elements -- provides information about the creation, revision, publication of a finding aid -- information about a body of archival materials at collection level -- description of subordinate components; hierarchical

28. Sample elements

29. Attributes for type= era= calendar= normal= certainty= encodinganalog=

30. Example <unitdate type="inclusive" encodinganalog="245$f“ era="ce" calendar="gregorian" normal="1895/1962"> 1895-1962

31. Sample elements -- [subgroup] – -- [series] <unittitle --[item or folder]

32. Back to Alice Edwards … Look at various pieces of encoded finding aid.

38. Search Retrieve Display Exchange Retain hierarchy of folder- or item-level description. Primary Reasons

40. Disclaimers NWDA database under development. Being moved to new server at this time. Stylesheet being enhanced and customized. Search engine not customized yet. Database only includes ~300 XML files at this time.
