Web of Data

Meta Trend

Spatial Data on the Web

Title

Web of Data

Description

Data published on the web are made discoverable, accessible and interoperable using WWW best practices for data formats, data access, data identifiers, metadata, licensing and provenance.

What is new or emerging?

- W3C Workshop on Web Standardization for Graph Data (March 2019): Support for adding geospatial and temporal to graph query languages

- Emerging progress on Property Graphs standards in JTC 1 SQL (June 2019): Property Graph Queries as a new part of SQL standards, 9075-16 and New declarative property graph language.

- Schema.org and JSON-LD

Why might it matter?

- OGC Environmental Linked Features Interoperability Experiment: Power of OGC APIs to expose features in the context of rich domain-feature-model-based linked data while following W3C best practices

- Advantages similar to adding Topology to Geometry queries.
