The following is a listing of projects that ADIwg has sponsored.
Project Metadata
In 2010, ADIwg adopted a set of common fields for use in exchanging discovery level information about the who, what, when and where of projects in Alaska. In order to expedite the exchange of information, these fields were mapped to an Extensible Markup Language (XML) schema released in 2011. Some agencies provide project information as static XML documents and others have implemented RESTful endpoints to facilitate access to updated information.
Due to the importance of data integration with our international partners, ADIwg chose to base future versions on the ISO 19115/19110 family of metadata standards.
Project Metadata Standard (ISO)
The current version of ADIwg Project metadata has been mapped to ISO 19115/19110. Due to the complexity of the ISO standards, ADIwg chose simplify implementation by creating an ISO-compatible JSON standard. The JSON serves as a lightweight alternative for sharing metadata amongst ADIwg members. The mdTranslator application allows conversion to other formats for sharing with external partners.

Project Metadata Standard (FGDC) 1
The original version of ADIwg Project metadata mapped many of the fields to the Federal Geographic Data Committee (FGDC) metadata standard and Keyhole Markup Language (KML) for spatial domain information.

Data Metadata Standard
The ADIwg Data metadata standard has been mapped to ISO 19115/19110. Data metadata is also supported by an ISO-compatible JSON standard. The JSON serves as a lightweight alternative for sharing metadata amongst ADIwg members. The mdTranslator application allows conversion to other formats for sharing with external partners.

mdJSON Schemas
ADIwg has developed a set of JSON schemas to provide documentation and validation for project and data ADIwg JSON metadata.

mdTranslator
To support the JSON standard ADIwg is developing the mdTranslator, a software ‘engine’ that converts metadata in the ADiwg JSON structure to other metadata formats, including ISO 19115-2. While the mdTranslator’s primary purpose is to transform metadata stored in the ADIwg JSON standard, the architecture of the translator allows for possible conversion between many other formats. The basic process is illustrated in the figure below:
The mdTranslator isolates metadata creators from the complexity, rigor, formatting, and terminology of the output standard - a significant benefit when the output is based on the ISO 19139 XML Schema.
