Goals for Today Identify sources for collecting, enhancing, and redistributing siloed metadata Describe strategies to collect and re-use descriptive metadata Identify the tools used for metadata transformation
“Metadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource.” (NISO, 2008)NISO, 2008 Ideally, metadata is “good” and “shareable” Conforms to standards Uses authority control High quality & reflects consistent practice Includes terms of use Is coherent Provides context Supports long term preservation Should be authoritative, authentic, archivable, persistent and unique Optimized for interoperability (NISO, 2007(NISO, 2007 and Shreeves et al., 2006) Metadata: Essential to Discovery Image©2006 Saltatempo Saltatempo

What descriptive metadata silos exist at your institution? (select all that apply) A. Integrated Library System (ILS) B. Institutional repository C. Digitized archival collections D. Campus systems E. Homegrown or other systems
Silos as Sources ILS Campus Systems Digitized Archival Collections Homegrown Other Sources Institutional Repository
Silos as Sources From ILS to IR –Authority records From IR to ILS –Extracting specialized abstracts, descriptors Excel spreadsheet to IR From homegrown database to IR
Breaking down the walls ILS Campus Systems Digitized Archival Collections Homegrown Other Sources Institutional Repository
Metadata Extraction Metadata planning o Repository metadata o Project level metadata Extracting existing metadata Modifying extracted metadata
Metadata Planning: What do you want? Develop metadata guidelines for your IR o Schema, elements, data formatting o Required elements vs. Optional elements Some considerations: o Object formats o Audience o Resource management needs o Sharing/Interoperability
Metadata Planning: System Considerations Reconciling what you want with what you can have o System requirements o User Interface requirements Schema Indexing Display Be Flexible!
Project Level Metadata: Assess and Map What metadata do you have? What metadata do you want or need? How can you get it? o Create new metadata for Repository objects o Re-use existing metadata o Hybrid of new and existing Crosswalk to your Repository guidelines
Metadata Extraction: Re-using Existing Metadata From Integrated Library System o Z39.50 o MARC21 to MARCXML From internet o XML files From databases or spreadsheets o Tab delimited to XML o XML to XML
Metadata Extraction: ILS Metadata
Metadata Extraction: Internet
Metadata Extraction: Spreadsheet/MS Excel
Metadata Extraction: MS Excel to oXygen
Metadata Extraction: Database
Modifying Extracted Metadata Transform the metadata o Use the crosswalk as a guide Title = = o XSLT (eXtensible Stylesheet LanguageTransformations) a language for transforming XML documents into XHTML documents or to other XML documents – W3CW3C Some pre-existing tools o MarcEdit o Library of Congress
XSL Transformations MARCXML to DC XSLT (snippet) :
XSL Transformations MARCXML in … Seuss, Dr. The cat in the hat, by Dr. Seuss. … DC out The cat in the hat, Seuss, Dr. …
Summary Silos need not be insurmountable barriers to sharing metadata Existing metadata in xml format can be manipulated to fit individual repository needs Be creative – think outside the box!
