The query is in SPARQL, and the application only specified that the result should be returned in JSON format. So, in this case Raitis, in the application, loops through the results and creates the features to be displayed. Hence, no particular JSON schema is used, the JSON returned is based on the query columns.

ETF (European Testing Framework (http://docs.etf-validator.net/v2.0/index.html) validator
ETF is an open source testing framework for validating spatial data, metadata and web services in Spatial Data Infrastructures (SDIs).
The design of ETF is driven by three goals: be user-friendly, consistent with the standards and capable of testing all resources in an SDI.
User-friendly means that you do not have to be a developer to use it and that test reports include sufficient information for technical staff to understand the reasons for warnings and errors detected during the execution of tests. The user interface and the test reports support multiple languages, too.
The concepts in ETF are based on ISO 19105 and the OGC Specification Model which underpin the standards used in SDIs. Tests are organized in Executable Test Suites, which may be developed and executed using different tools to properly support all kinds of resources in an SDI. Currently supported are:
· SoapUI, a widely used tool for testing web services
· BaseX, an XML database, for testing sets of XML documents - including very large ones
· TEAM Engine, the tool used by the OGC CITE tests, to support the modern CITE tests developed using TestNG

"The API SITNA is a JavaScript API that enables us to include an interactive map viewer, representing geographically referenced information, in web pages and web application.

This SITNA product has been developed to be used in the web applications of the Government of Navarra. However it can be used by any user or organization in their web pages.

The API SITNA currently provides the following functionality:

- Navigation tools included in common map viewers, such as zoom, location map and basic measuring tools.
- Searches by municipality name, address, cadastral parcel or coordinates, among other options.
- Configuration default facilitates the creation of a basic map of Navarra with common tools and four background maps from IDENA , - specifically orthophoto, base map, topographic mapping and cadastre-.
- Possibility to add geo-information using WMS and WMTS services.
- Creation of specific markers with associated information.
- Geospatial information can be uploaded from a KML file.

The API is based on various third-party JavaScript libraries, but it is completely self-contained. All the related resources are dynamically loaded by simply inserting the API script in the page. This development approach has as a main goal to make API accessible for developers with a limited GIS knowledge."

As one from API candidate for INSPIRE hack we recognize HS Layers NG Map composition scheme supporting combination of data and services in different format (WMS, WFS, WCS, KML, GeoRSS, GML, GeoJSON, RDF and SOS.). i.e. detailed definition and metadata of each layer of the composition along with the composition itself, it can be saved as a JSON-styled text document. This JSON style document, is now used by Map Composer for creating of map composition. Map composer is providing the necessary functionality for displaying spatial data on a map and then creating a map composition (a thematic map) that can contain several data layers. Then, this document can be read and visualized by an HSLayers NG (http://ng.hslayers.org/ ) -based web application. This concept was used for by SDI4Apps, Open Transport Net and FOODIE project and now is supported in PoliVisu, EUXDAT and DataBio projects. See detail scheme https://github.com/hslayers/hslayers-ng/wiki/Composition-schema. The idea is to test this scheme by other platforms.
