About Project 418

Philosophy: #UseThePlatform

Keywords: Semantic metadata, HTML5 (microdata), hypermedia, web components, web architecture

Mission: Demonstrate and facilitate self publication and consumption of semantic metadata on the web following web architecture patterns via HTML5 microdata for the geosciences data facilities.

Introduction

Project 418 (named for April 2018 when the project ends) leverages off patterns explored by the EarthCube Council of Data Facilities (CDF) Registry Working Group (RWG).

Some key elements of this approach will include:

Leverage web architecture approaches to allow access to self hosted semantic metadata

This leverages HTML-5 microdata approaches combined with the schema.org vocabulary extended with community vocabularies/ontologies following established external vocabulary practices established by the schema.org governance.

Generate indexes of this metadata following web architectural approaches to harvesting

Tech notes: The harvesting will follow web architecture practices as well. This leverages hypermedia patterns that are present as part of the web architecture to provide approaches to navigating networks of semantic metadata. These indexes would provide textual, spatial and graph representations of the exposed semantic metadata.

Facilities would expose information about data and service resources for the initial phase

Tech notes: Key types exposed will include schema.org/DataSet and schema.org/DataCatalog leveraging work with schema.org led by RPI to establish these key types. Additionally work by the CDF RWG leveraging re3data resources will provide guidance on exposing information about a facility in general and also related to service endpoints (RESTful, OGC, others). This will be done following HTML5 microdata approaches using JSON-LD as a publishing approaches.
