## Outline

**What is metadata?**
**What is the Goddard Core?**
**How does the Goddard Library use it with web sites?**
**What is the DAS framework?**
**What are the benefits?**

## What is Metadata?

**Data about data**
**“****Header information”**
**Common standards like those used in library catalogs: author, title, etc.**

## What is the Goddard Core? 

**Goddard Core Metadata Element Set**
**Based on the ISO Standard for Descriptive Metadata (Dublin Core)**
**Extends the Dublin Core to 24 qualified descriptive elements.  There are additional Administrative Elements.  Preservation Elements are being developed.**
**Enables custom classification of GSFC-specific content**
**Examples: Contributor.RNO, Contributor.Webmaster**
**Goddard Core was extended to accommodate GSFC project-specific needs**
**Supports evaluation and resource discovery of project-oriented information**
**Examples: Subject.Instrument, Subject.Competencies**

## Meta-Tagging for Web Pages

**Required metadata fields for Goddard Sites**

| Web Guidelines | Goddard Core |
| --- | --- |
| Title | Title |
| Description | Description |
| Orgcode | Creator.code |
| Content-owner | Contributor.contentowner |
| RNO – Responsible NASA Official | Contributor.rno |
| Webmaster | Contributor.webmaster |

## Preserving Web Sites

**Capturing project Web Sites**
**Metadata Creation**
- Extract and map from available meta-tags
- Inherit from these meta-tags to lower level sites that don’t have any based on rules
- Manually add remaining metadata
**Store metadata in separate file to preserve the original web site**

## Taxonomy/Controlled Vocabulary

**NASA Taxonomy developed by JPL serves as the primary taxonomy for the Digital Asset System**
**Project-specific taxonomies/controlled vocabularies include:**
**Earth Observing System (EOS)**
**Landsat**
**Swift**
**Web Content specific controlled vocabularies include:**
**Content Type**
**Format**

## Benefits of Applying Goddard Core Metadata

**Organize and manage content across collections and formats**
**Re-use & re-purpose web content**
**Provide metrics for web content **
**Support access, display, and personalization**
**Aids long term preservation and access **
