What is metadata

What is Metadata?

Information about an information resource of any media type or format.

Metadata Fundamentals for All Librarians, Priscilla Caplan, 2003.

Information To…..

  • Identify

  • Find

  • Access

  • Manage

  • Help in using the data


Community specific metadata

Community Specific Metadata

  • TEI

  • EAD

  • VRA

  • DDI

  • CSDGM

  • (FGDC)

describe works of visual culture and images.

  • standard for encoding finding aids so that they can be searched and viewed online

  • standard for description of social and behavioral sciences datasets

metadata for describing structural divisions in text

metadata for describing maps, and geospatial datasets


General metadata schemes

General Metadata Schemes

  • MARC

  • Dublin Core

  • METS

  • MODS

  • GDMS

  • DescMeta

  • Library of Congress metadata for describing complex digital library

  • Objects. It encodes descriptive, administrative, and structural metadata

Descriptive metadata, derivative of MARC21

  • Developed by UVA’s Digital Research and Development Group for collection and data objects

Format used in traditional libraries

A simple international standard metadata for

describing digital resources across disciplines

UVa’s descriptive metadata for Digital Library objects


Cross discipline project

Cross Discipline Project

  • Digital Library Research and Development

  • Brown Science and Engineering Library

  • Geospatial and Statistical Data Center

  • Civil Engineering

  • Systems and Information Engineering

  • Various Undergraduate and Graduate Students


Project goals

Project Goals

  • To provide easy access to a diverse collection of data resources about Virginia

  • To design a general approach to collection building (and metadata) that can be applied to all kinds of statistical and science datasets


Project scope

Project Scope

  • United States Census of Population and Housing 2000, Virginia: Summary File 3

  • Virginia Department of Transportation (VDOT) Intelligent Transportation System (ITS) Data

  • National Climatic Data Center (Virginia), Climate Surface Data


The data problem

The Data Problem

  • Three different datasets

    • Space and time

    • Definitions and terms

  • Various “native” data formats

  • SPSS

  • Comma Delimited

  • Oracle Database

  • Lots of Data for Virginia

  • 135 counties, 48 files each (Census)

  • 1948 – 2005, 1326 historical & active stations (Climate)


Simplifying the problem

Simplifying the Problem

  • Choosing a subset of the data to test the design

  • Breaking the data down into smaller parts;

    defining “Datasets Objects”

  • Choosing a common file format; creating “Database Objects”

Dataset object metadata

Dataset Object Metadata

  • Metadata Purpose

To describe the hierarchical dataset

To use for discovery

To tie the datasets together

  • Metadata Standard

GDMS (General Descriptive Modeling Scheme)

Position for use in UVa’s Digital Library


Database object metadata

Database Object Metadata

  • Do the datasets have “native” metadata?

  • What existing standards are best suited for numerical data? FGDC? DDI?

  • Other Considerations?


Choosing a standard

Choosing a Standard

  • Review of FGDC and DDI with the following criteria:

    • Data file description as a whole

    • Physical description of the file format

    • Variable level description

    • Variable, physical description


Using the ddi standard

Using the DDI Standard

  • Created a Data Dictionary

    • Applying the Digital Library’s Minimum Metadata Requirements

    • Using only metadata elements that apply to these database objects and the project


Training with metadata

Training with Metadata

  • Instructed members how to create DDI files

    • Advised on metadata content

    • Created DDI-XML Template

  • One-on-one training with Nesstar Publisher

    • Created Nesstar Templates

  • One-on-one and group training on GDMS

Images


Reviewing metadata

Reviewing Metadata

  • Checked sample DDI mark-up files

  • Discussed the use of other DDI elements

  • Group review of GDMS output

  • Review of Metadata is continuing


Results

Results

  • Demo of Modeling Virginia (Census Data)


What i learned

What I Learned

  • All data objects are different and each have different metadata needs

  • Be clear, consistent and specific

  • Don’t be afraid to alter standards to fit your need: Document your Practice!

  • Metadata must be reviewed and reviewed

  • Include information creators in metadata creation.
