MENDS

NASA ESDIS has formed a team of data systems and metadata experts to analyze requirements and recommend the best approach for NASA Earth Science data systems to align with the international metadata standard ISO 19115. The team considered the applicability, limitations, and possible profiles of this standard for the diverse data sets maintained by NASA data centers and missions. The team’s initial findings and recommendations regarding to how reach the interoperability goals of NASA using these standards will be discussed. We are also pleased to have David Danko, lead of the Project Team revising the ISO 19115 standard, attending the session. He will describe the current status of the revision process and discuss applications of ISO 19115 to data quality and lineage metadata.

Notes from Session

Session Goals
- Status of ISO 19115
- Applications of ISO 19100
- Gather feedback from MENDS team memebers
Procedural Matters
- Report synopsizing activities, discussions, and future action items due at the end of the meeting
- Post notes soon after the session and invite feedback
- Coach rapporteur for expected key points/action items
Origins of MENDS
- NASA ESDIS assembled experts from a variety of sources and directed them to study metadata and analyze whether or not it meets stakeholder needs
- It's not just 19115, also many other ISO 19100s metadata models
Metadata Uses
- Starts with a mission or project that has data which flows to a data center/archive
- Users can access metadata through search and order tools in metadata directories
- describe => serve => use
MENDS process
- Phase I (Aug '10 - Jan '11)
- Understand metadata usage
- Collect stakeholder requirements and concerns
- Develop use cases detailing metadata flows
- Analyze data and make recommendations
- Deliver technical paper to ESDIS
- Describe benefits of ISO 19115+ over existing metadata
- Assessment of impacts on existing systems
- Propose methods for adopting ISO
Key Findings
- Adoption of ISO 19115+ is a logical step for NASA earth science data systems
- Common usage across NASA systems is desirable
- Must avoid pitfalls of rushing to develop a profile
Next Steps
- Submit technical report detailing recommendations
- Research issues in Phase I
- Develop tools
Summary
- ISO 19115 presents tremendous depth and flexibility
- Demonstrating benefits is better then mandating standards
- ESDIS has the opportunity to play a leading role

ISO TC 211 Metadata Standards

Existing standards - many ISO 19100s standards
Official scope
- Schema for describing geographic information and services
- extent, quality, spatial, and temporal metadata
- applicable to cataloguing
- may be used for existing maps/charts
- Defines metadata elements
- Provides schema (UML)
- Establishes a common set of metadata terminology
Implementation
- Many organizations have implemented it
- Many metadata editors have incorporated it as a format
Revisions
- ISO 19115:2003 Data Quality Information
- Lineage
- Data quality classes
- New Metadata Schema

Discussions

Comparison of ISO and XML
- Many many XML tools out there
- NASA has a lot of experience with XML systems
- Very different landscape than it was previously
Adoption is important
New revisions can change the definition of bands of coverage
Extensions could be added instead of major schema changes
- To make revisions, find test cases that need that change

Report

Eight recommendations in the executive summary
Next step with regard to tools and implementation plans
A big challenge is to ease the entry and demonstrate the benefits of 19115
