Introduction to the Metadata Enterprise Resource Management Aid (MERMAid) Kathy Martinolich

MERMAid (Metadata Enterprise Resource Management Aid) is a web application developed by NCDDC to facilitate the generation, validation, and management of coastal metadata. It supports various metadata standards, offers robust validation and import/export capabilities, and provides management features for organizing and regulating workflow.

  1. Introduction to the Metadata Enterprise Resource Management Aid (MERMAid) Kathy Martinolich Jacqueline Mize NOAA National Coastal Data Development Center

  2. NCDDC Mission • “Provide access to coastal ecosystem data . . .” • Accomplished via the development and cataloging of • coastal metadata for data discovery & access • NCDDC seeks to facilitate the process of submitting • coastal metadata for cataloging • Data providers need a simple way to generate, validate • & manage their metadata • Metadata Enterprise Resource Management Aid

  3. MERMAid Technical Elements • Developed at NCDDC, MERMAid uses the framework • of NCDDC’s web application server, the • Z-Object Programming Environment (ZOPE) • Open-source • leverages outside resources • freely distributable • Utilizes an object-oriented database available in ZOPE • Offers secure, remote access through a web browser • (https://mermaid.ncddc.noaa.gov)

  4. MERMAid Capabilities • Generate FGDC Standard, Biological, and Shoreline Profile and Remote Sensing Extension Records • Supports Ecological Metadata Language (EML) • Enhanced validation / continuous validation • Import existing FGDC records in XML and TXT format • Export records in XML, TXT, HTML or MARCXML • via “save as” • Robust “Help” functions • - FGDC Standards & Workbook contents • Contents of records stored as generic objects in OODB • - Offers ease of crosswalk implementation

  5. MERMAid Management Features • Metadata provider can: • Organize metadata • Establish unlimited metadata databases • - Group records as needed • (by program, project, data type, personnel …) • Regulate workflow • - Establish manager & custodian roles & permissions • (Resource, Data Source and Database level) • - Monitor record status using knowledge-based • search capability (near future)

  6. More Management Features • Metadata provider can: • Store supplemental information associated • with a record or data set (documents, correspondence,…) • Operate as a standalone “in the field” • - Synchronize with central repository • via remote log-in • - “Back-up/restore” between independent • MERMAid systems

  7. MERMAid Continuing Development • Automate translation from FGDC to other standards • - Dublin Core, DIF, ISO, MarineXML, TransducerXML • Import / Export records in “batch” mode • Facilitate harvesting or exchange of large number of • records or data sets • Evaluate need for various custom extensions • NOAA, ESRI … • Direct access to controlled vocabulary databases • ITIS, GCMD, ASFA …
