Describing Archives: A Content Standard
“rules to ensure the creation of
consistent, appropriate, and self-
explanatory descriptions of archival
material.”

15. I. Basics - A Brief Aside: DACS
“DACS defines twenty-five elements that
are useful in creating systems for
describing archival materials.”
15
16. I. Basics - A Brief Aside: DACS
Seven Element Types
• Identity
• Content and Structure
• Conditions of Access and Use
• Acquisition and Appraisal
• Related Materials
• Notes
• Description Control

17. I. Basics - A Brief Aside: DACS
“Not all of the DACS elements are
required in every archival description.”

18. I. Basics - A Brief Aside: DACS
Statement of Principles
Principle 7: Archival descriptions may be
presented at varying levels of detail to
produce a variety of outputs.
18
19. I. Basics - A Brief Aside: DACS
Principle 7
• 7.1: Levels of description correspond to
levels of arrangement.
• 7.2: Relationships between levels of
description must be clearly indicated.
• 7.3: Information provided at each level
of description must be appropriate to
that level.

A Component <c> provides information about the content,

Each <c> element identifies an intellectually logical section
of the described materials. The physical filing
separations between components do not always
coincide with the intellectual separations.

59. III. Implementation: Using EAD
Other Uses
• Integration with other standards (e.g. EAC-CPF)
• Open Archives Initiative – Protocol for Metadata
Harvesting (OAI-PMH)
• EAD consortia
• Metadata for digitized collections

66. III. Implementation: Using EAD
Tinker!
• Learn more about XML and XSLT
• Download the free trial of oXygen XML editor,
the schema, an EAD finding aid, and a stylesheet.
• Try some basic actions: add a folder, change a
controlled vocabulary term, remove a series.

• Reduce semantic overload
• Simplify and standardize links
• Reduce mixed content
• Add, deprecate, and delete elements

68. III. Implementation: Using EAD
The Future of EAD
• Revision is schema-based – goodbye, DTD
• LC stylesheet: dtd2schema.xsl
• “Attribute validation errors indicate that the
attribute value does not conform to the ruling
ISO standard”

70. III. Implementation: Using EAD
The Future of EAD
“In an ideal world, EAD and EAC-CPF would be
opaque to all but a few expert users, created when
needed as secondary outputs from efficient and
adaptable software tools with archivist-optimized
interfaces.”

71. III. Implementation: Using EAD
The Future of EAD
“This next wave [of archival standards] is going to
push beyond online versions of print-based
document genres and embrace the Web as the
native format for description—dynamic, diverse,
and discoverable description.”

Familiar with html? Similar (tags aka mark-up), but data structure, not displayXML (eXtensible Markup Language): set of rules for structuring data via markup
DTD and schema define the buckets; the list of tags in the tag library (we’ll see later) is defined here. Move to schema is coming; more flexible; not something you need to know right awayhttp://www.flickr.com/photos/linneberg/4481309196/sizes/m/in/photostream/
http://www.flickr.com/photos/johnkay/3539126525/sizes/m/in/photostream/Note that it is hierarchical – nested. Parent elements apply to child elements.
Encoding standards are rules for defining buckets; content standards are rules for the information insidehttp://www.flickr.com/photos/linneberg/4481309196/sizes/m/in/photostream/Xml, EAD, MARC are ways to structure your data, they are not the same as the descriptive data such as the finding aid, the catalog record, etc.

An EAD-encoded finding aid is split into info about institution/FA (metametadata) and info about materials (the finding aid)
A required subelement of <eadheader> that designates a unique code for a particular EAD finding aid document. Two of the attributes, COUNTRYCODE and MAINAGENCYCODE, are required to make the <eadid> compliant with ISAD(G) element 3.1.1. MAINAGENCYCODE provides the ISO 15511 code for the institution that maintains the finding aid (which may not be the same as the institution that is the custodian of the materials described). COUNTRYCODE supplies the ISO 3166-1 code for the country of the maintenance agency. In addition to these two attributes, it is recommended that repositories also use at least one of the following attributes: URL, PUBLICID, or IDENTIFIER to make the <eadid> globally unique. PUBLICID should be a Formal Public Identifier, URL an absolute or relative address, and IDENTIFIER a machine-readable unique identifier for the finding aid file.

“ICA-AtoM is web-based archival description software that is based on International Council on Archives ('ICA') standards. 'AtoM' is an acronymn for 'Access to Memory'.”
Basic, powerful XML editor. You can safely ignore about 95% of the buttons and drop-downs, but will do things like suggest valid tags and attributes, close tags, and validate as you go. This is what we use.

XSLT (Extensible Stylesheet Language Transformations) is a declarative, XML-based language used for the transformation of XML documents. Here, the EAD tag processinfo is converted into HTML.
