The ultimate goal of the initiative is to achieve the publication of as much data as possible, using structured formats, preferably non-proprietary and automatically processable.
The better structured and enriched the data, the easier it will be to reuse it and to build applications for automated processing. The use of open standard formats will allow data to be processed with various types of tools without having to acquire user licenses.
Among the most common open formats that are distributed through this initiative are :
- PNG
- JPG
- GIF
- TXT
- HTML
- HTM
- XML is a tag-based metalanguage used to represent structured information. It is one of the most widely used formats for the sharing of structured information: between programs, between people, between programs and people, both locally and online.
- JSON is a lightweight format for data exchange. This format is a subset of JavaScript's object literal notation that does not require the use of XML. Its simplicity has led to the generalization of its use, especially as an alternative to XML in AJAX
- RDF is a model for the representation of information on the Web using expressions with the form subject-predicate-object. The subject is the resource that is described, the predicate is the property on which the resource is to be established and the object is the value of the property with which the relationship is established. The combination of RDF with other tools allows adding meaning to pages and is one of the essential technologies for the semantic web. In order to be interpretable, it is rendered in XML format.
- OWL
- N3
- TURTLE
- ATOM
- RSS is an XML- based data format used to broadcast content to website subscribers. They are typically used for descriibir briefly update content which is quite frequent. To access this information, specific programs or functionalities available in web browsers are used.
- CSV is a simple open format document type to represent data in table format, in columns separated by commas (or semicolons, where the comma is the decimal separator) and the rows are line breaks. The extensions that are used are. csv and. txt . It corresponds to the MIME type text / csv .
- KML is an XML- based markup language for representing geographic data in three dimensions. Its grammar contains many similarities to that of GML . It contains a title, a basic description of the place, its coordinates (latitude and longitude) and some other information.
- GML
- GEOJSON
- WKT
- WFS is a web service that allows to interact with the maps served by WMS using the GML language , derived from XML . It allows recovering vector data and the alphanumeric information linked to them, also allowing both spatial and alphanumeric queries. Its specification is collected in OGC .
- WMS Web service in open standard format that produces spatially referenced data maps via http, dynamically from geographic information. Its specification is collected in OGC .
- ngsi10
- XLS / XLSX is the Microsoft Excel file format. It is a spreadsheet application that is part of the Microsoft Office suite. It is an application used in financial and accounting tasks, with formulas, graphics and a programming language.
