W3C and OGC put more Spatial (and space-born) Data on the Web

5 January 2017 | Archive

The Spatial Data on the Web Working Group, a collaboration between W3C and the Open Geospatial Consortium, has published 4 documents today. QB4ST adds extensions to the RDF Data Cube for spatio-temporal components. These are designed to make it easier to share and manipulate data such as Earth Observations with linkable slices through time and space. The QB4ST extensions are used in another of today’s publications, Publishing and Using Earth Observation Data with the RDF Data Cube and the Discrete Global Grid System, which shows how SPARQL queries can be served through OGC’s developing Discrete Global Grid System for observations, coupled with a triple store for observational metadata. The approach makes use of the power of Linked Data on the Web without requiring all data points to be encoded as RDF triples.

The latest Working Draft of the Semantic Sensor Network Ontology sets out a modular approach that allows alignment with related vocabularies. The modular architecture supports the judicious use of “just enough” semantics for diverse applications, including satellite imagery, large scale scientific monitoring, industrial and household infrastructure, citizen observers, and the Web of Things. Finally, the Working Group is pleased to publish an update to its Spatial Data on the Web Best Practices document that advises on best practices related to the publication and usage of spatial data on the Web; the use of Web technologies as they may be applied to location.

Updated Resources: Planning and Managing Web Accessibility

22 December 2016 | Archive

The Education and Outreach Working Group (EOWG) has updated three resources. Planning and Managing Web Accessibility helps you integrate accessibility throughout the Web production process. It applies to individual projects and at the organizational level. Developing Organizational Policies on Web Accessibility helps you develop a simple or comprehensive Web accessibility policy for an organization. Web Accessibility First Aid: Approaches for Interim Repairs is intended to help with the situation: "I need to make my website accessible and I don’t even know where to start!" It provides guidance on addressing short-term accessibility fixes. Read more about the Web Accessibility Initiative (WAI).

Updated: Easy Checks, A First Review of Web Accessibility

22 December 2016 | Archive

The Education and Outreach Working Group (EOWG) has updated Easy Checks – A First Review of Web Accessibility. This resource helps you start to assess the accessibility of a Web page. With these simple steps, you can get an idea whether or not accessibility is addressed in even the most basic way. These checks cover just a few accessibility issues and are designed to be quick and easy, rather than definitive. This update includes a new check on Moving, Flashing, or Blinking Content and instructions for the Web Developer Toolbar for multiple browsers.

W3C Invites Implementations of Activity Streams 2.0 and Activity Vocabulary

15 December 2016 | Archive

The Social Web Working Group invites implementation of two Candidate Recommendations:

  • Activity Streams 2.0: This specification details a model for representing potential and completed activities using the JSON format. In the most basic sense, an “Activity” is a semantic description of an action. It is the goal of this specification to provide a JSON-based syntax that is sufficient to express metadata about activities in a rich, human-friendly but machine-processable and extensible manner.
  • Activity Vocabulary: This specification describes the Activity vocabulary. The Activity Streams 2.0 Vocabulary defines a set of abstract types and properties that describe past, present and future Activities.
