3
Factors affecting selection of metadata Metadata schema Content standards Software Target audience How is it being created or supplied? Functions it serves
4
Metadata schema MARC21 Dublin Core VRA Core EAD ONIX GILS CSDGM/FGDC
5
Content standards AACR2/RDA Western States Dublin Core Metadata Best Practices LCSH, TGM, AAT, ULAN, and other controlled vocabularies
6
Software considerations Underlying metadata it supports or requires OAI compatible Ability to export metadata from the system Labels and ease of changing them Ability to customize fields for display and searching Default public records Built-in search interfaces Support for authority control Global change capabilities Administrative interface
7
Target audience General public Academic (K-12, college, university, students, teachers, etc.) Specialized discipline (artists, economists, scientists, etc.) Distinct cultural community (native peoples, ethnic groups, linguistic groups, etc.) Age Impairments (vision, hearing, dyslexia, literacy) Open or restricted access
8
How is it being created or supplied? Human supplied Trained staff or the general public Machine generated
9
Functions it serves Descriptive or discovery Administrative Technical or preservation Relationship or linkage Structural metadata
10
Dublin Core Metadata Element Set 15 optional and repeatable elements Widely touted for interoperability – OAI Supposed to be easy to apply Criticized for lack of content standards for most elements Criticized for leaving some key elements out and for unnecessarily duplicating others

Logical or useful presentation
13
Metadata challenges for group projects Field labels Content standards for fields Searching aggregated metadata
14
Metadata challenges Project participants have agreed to follow the Western States Dublin Core Metadata Best Practices, version 2.0 The standards provide considerable latitude for some elements Some participants are harvesting from legacy collections that were created without reference to these standards
15
Application of metadata standards Digitization Specifications Mandatory and repeatable Not mapped to a Dublin Core element Refers to a variety of standards Lot of local latitude in: labeling field input standards
16
Application of metadata standards Date.Original and Date.Digital Both fields are mandatory (when applicable) Western States Best Practices document gives clear guidance Both map to Dublin Core Date Both say to follow W3C – Date Time Format yyyy-mm-dd (1897-07-16 for July 16, 1897)
17
No mapping to encoding schema
18
Inconsistent search results
19
Type recommendations
20
Advanced search
