## The Challenge

- Supporting metadata formats can be a challenge. The basic FGDC format contains over 300 fields. There are various FGDC profiles, including Biological, Shoreline and Remote Sensing, which add even more fields. We need a tool that supports creation, editing, storage and public search.

## Overview

- NOAA Metadata Manager and Repository (NMMR)
- Developed by NGDC and NODC
- Supports multiple metadata standards
- Web, SOAP, and search interfaces
- Creation of metadata, with minimal understanding of FGDC standards
- Supports workflow with multiple states
- Collection/granule (parent/child) record sets

## Plumbing

## Process

- Create metadata template
- Create records
- Create
- Validate
- Approve
- Publish

## Metadata Templates

- Metadata types are defined by creation of templates that specify elements
- Data types and valid values
- Required or optional
- Repeatable
- Record structure
- Component records for common elements
- Currently support basic FGDC, plus Biological profile and Remote Sensing extensions
- Expect to support ISO 19115/19139
