Implications of Linked Data for GEOSS

This page will discuss the possible ways in which the concept of linked data can be used for data, metadata, semantics etc. throughout GEOSS. This would potentially be a major shift for GEOSS, since linked data is very semantically driven. However, the thought could be that the GCI components be modified over time to deal with linked data while there is an education and outreach effort to get data providers to convert to linked data usage. The long term goal is that more and more linked data will be used, resulting in greater benefit to GEOSS users and providers.

The initial effort, coming from the SIF, is to identify, analyze, and recommend some best practices and guidelines for using linked data. The SIF will also study and recommend how GCI components can be modified to exploit linked data if it is available. This effort is not meant to disrupt any existing operations.

Identifed Best Practices and Guidelines for Linked Data

  1. W3C Best Practices for Publishing Linked Data (W3C Working Group Note 09 January 2014)
    • http://www.w3.org/TR/ld-bp/
    • The W3C Best Practices address the Best Practices for distinct phases, summarised by the section headings extracted from the document;
  PREPARE STAKEHOLDERS SELECT A DATASET MODEL THE DATA SPECIFY AN APPROPRIATE LICENSE
GOOD URIs FOR LINKED DATA USE STANDARD VOCABULARIES CONVERT DATA PROVIDE MACHINE ACCESS TO DATA
ANNOUNCE NEW DATA SETS RECOGNIZE THE SOCIAL CONTRACT    
    • Consideration of all of the above aspects is key to implementing linked data solutions. For GEOSS and possible GCI implementation which areas should be focussed on? For example, can GEOSS define a policy for URI/IRI specification CF http://tools.ietf.org/html/rfc5870||RFC5870. For which categories can the GCI provide a service and for which parts does the responsibility lie with the data provider?
