1. ADIwg Update to AOOS 2013-14 project Making ISO metadata accessible
September 25, 2014
Stan Smith, USGS

2. Project Background Mission Phase II – support for DATA metadata
Adoption of ISO as standard
Agreed to share high investment cost of understanding and implementation
Implementation must support diversity of needs and technical requirements across ADIwg membership
Replace Phase I project standard based on FGDC
Work has been accelerated by …
Sharing workload among ADIwg membership
FY13 funding from National Climate Change and Wildlife Science Center (NCCWSC - USGS)
FY14 and FY15 funding from Community for Data Integration (CDI – USGS)
Work via ADIwg is largely on a “volunteer” basis, grants help accelerated the process since staff resource can be allocated directly.

3. Project Objectives (ISO)
Eliminate necessity to learn ISO family of standards
Make it easier for organizations to become ISO compliant
Integrate ISO support into local applications and services
Implement custom web services with integrated ISO metadata capability
Host a public web service for generation of ISO metadata records
Host a public web app for PIs to enter and edit metadata
Support both project and data metadata in ISO
Most important was to design an architecture that would allow all our organizations with their greatly varying requirements and technical abilities to benefit from the end products.

4. Current Project Scope In scope
Support creation of original metadata records
Use portable, open source code library
Create a user-friendly metadata preparation tool
Accommodate diverse needs and technical abilities
Extensible:
Accept input in multiple standards
Create metadata in multiple standards
Not in scope
Metadata clearinghouse (store & search metadata records)
Translation between XML metadata standards (e.g. FGDC->ISO)
Provide metadata snippets to other metadata tools

Third scenario is to host a web site to gather metadata on a web form.
Likely to imbed web form in a Rails 4 project.
Remember open-source: We want to be able to provide developers with a web form they can modify to keep pace with changes they make to the translator.
Hope to start work fall 2014.

9. Development Milestones
Support ADIwg Project Metadata standard
Refactor and Package mdTranslator as Ruby Gem
Complete Developer and User Documentation
Open REST endpoint to public
Provide web form access and code
Support ISO
Funded by CDI 2014/2015
Work In Progress
Determine Supported ISO Classes & Attributes
Build Example ISO XML
Verify Supported Fields List support for other standards
Design Translator Architecture
Draft ISO JSON Standard
Build JSON validator components
Build reader and writer components (JSON->ISO XML)
Host Demo for mdTranslator
Development will continue with or without CDI funding – just will proceed faster with funding
ADIwg needs to complete to satisfy requirement from ACCER
Also from IARPC (attached to OSTP) and the 2013 OSTP and OMB Memorandums
Funded by NCCWSC 2013
