From OCLC and MWDL Working Groups, 2009 -2010 New tools & guidelines to help From OCLC and MWDL Working Groups, 2009 -2010 New tools & guidelines to help with metadata • ‘Best Practices’ for CONTENTdm users creating shareable metadata • Mountain West Digital Library Dublin Core Application Profile • OCLC Digital Collection Gateway

Review of previous MWDL Metadata Guidelines (2006) • Clarify & refine Split Coverage element Review of previous MWDL Metadata Guidelines (2006) • Clarify & refine Split Coverage element into narrower Temporal and Spatial elements o Rename Digitization Specifications to Conversion Specifications o Adding MARC tag equivalents o • Improve harvesting o o Give more instruction on formatting Give more instruction on mapping • Improve searchability o Reliable date searching • Facilitate digital preservation o Add preservation fields for future migration of archival master files

 Solving problems with new guidelines Problem: When fields collide Data runs together illegibly Solving problems with new guidelines Problem: When fields collide Data runs together illegibly when multiple fields mapped into the same field Several solutions: • End each field with a semi-colon to separate data if mingled with another field • Begin second field with a prefix (ex. “Spine title”) to identify data in the field. • Map all but one multiple field “none” so that only one field harvested

Potato, Potahto, Potatoe Problem: Inconsistent use of metadata fields Temporal & Date fields o Potato, Potahto, Potatoe Problem: Inconsistent use of metadata fields Temporal & Date fields o o Temporal = time period covered by intellectual content Date = when digital object created Example: Book about Civil War written in 1922 Temporal = 1861 -1865 Date = 1922 Source & Relation: o Source = Information about an original resource from which the present digital resource is derived. o Relation = Another resource related to digital object

Type versus Format Adding MARC equivalent tags clarifies meaning of fields Format & Type: Type versus Format Adding MARC equivalent tags clarifies meaning of fields Format & Type: Which is which Important to use the correct field so search limits will work in MWDL Knowing the MARC fields these are crosswalked to is helpful: o Format: The file format, physical medium, or dimensions of the resource (image/jp 2, 45 minutes) § MARC 300 or 340 o Type: The nature or genre of the resource (image, audio, text) § MARC 655

Getting the date right and the right date Date search failure due to improper Getting the date right and the right date Date search failure due to improper date formatting Use date original item created Set data type to Date in field properties Format dates correctly o o yyyy-mm-dd (ex. 1776 -07 -04) yyyy-mm (ex. 1776 -07) yyyy (1999) yyyy-yyyy for date range (ex. 1901 -1967)

 "An application profile provides a standardized way to document the important decisions that have been made about the elements, including content standards and rules for use. Such documentation can facilitate migration, harvesting, and other automated processes.
