The New Standard for Library Data? Rob Kairis Library Director Kent State Stark Campus
Overview • The MARC Format • XML • Components of XML-formatted Data – XML Records (Metadata tags) – DTD (Document Type Definitions—Validation) – XSL (Stylesheets—Display Formatting) • Demonstration (Stark’s Rare Book Collection)
The MARC Format • Unique to Library Data • Complicated – NOT mnemonic (tags from 001 to 999) – NOT Self-defining (requires proprietary software) • Developed to Save Storage Space • Two Aspects to MARC – Logical Interpretation of the Data – The Physical/Communications Format

XML • Open Standard for ALL Types of Data • Simple – Metadata tags (self-defining data) <Author>Lief, Alfred</Author> – Does not require complicated programming • Can Be Used for Both the Bib AND Source Data • Biggest Problem – Records take up more storage space XML sample is 3 times larger than the MARC sample
Components of XML--DTDs • Outlines XML Content and Validates Record • Levels of MARC Verification: – Level 1: Basic ü No content verification – Level 2: Record-level (currently employed) ü Verifies that the record contains the correct sequence of field content: Ø 1 leader Ø 1 or more control fields (fixed-length) Ø 1 or more variable-length fields (includes subfields) – Level 3: Field-level (future) ü Ensures that certain fields are present, only standardized subfields are used, etc.

Components of XML--XSL • Provides a Structured Display for XML – Compares Templates to XML Elements – Transforms Semantic Markup to Presentational Markup • XPath – Used to Search for Specific XML Records
Demonstration (Stark’s Rare Book Collection) • • Collection of About 600 Items Exported as MARC from Kent. LINK Converted to XML HTML Created, Loads: – XML File – DTD – XSL (Using XPath) • Searches for Specific Records Using MARC Tag
