==== OGC - Open Geospatial Consortium ====

Organização sem fins-lucrativos formada por +/- 380 instituições voluntárias de vários países que, desde 1994, define padrões de:

  * Conteúdo e de serviços geoespaciais
  * Processamento de dados SIG
  * Compartilhamento de dados

== Padrões de meu interesse ==

  * [[Web Map Service|WMS]] - Web Map Service: mapas em forma de imagens.
  * [[wfs|WFS]] - Web Feature Service: Manipular features (abstração de fenômenos).
  * [[Web Coverage Service|WCS]] - Web Coverage Service: Provide [[Coverage data|coverage objects]] from a specified region.
  * [[Web Processing Service|WPS]] - Web Processing Service: Remote processing service.
  * [[Web Catalog Service|CSW]] - Web Catalog Service: Access to catalog information.
  * [[Simple Features|SFS]] - Simple Features - SQL
  * [[Geography Markup Language|GML]] - Geography Markup Language: [[XML]] format for geographical information.
  * [[Keyhole Markup Language 2.2|KML]] - [[Keyhole, Inc|Keyhole]] Markup Language: [[XML]]-based language schema for expressing geographic annotation and visualization on existing or future Web-based, two-dimensional maps and three-dimensional Earth browsers.
  * [[Web Service Common|OWS]] - OGC Web Service Common

These were originally designed around the [[HTTP|HTTP]] web services [[paradigm]] for message-based interactions in web-based systems. However, in the last year the members have been working on defining a common approach for [[SOAP (protocol)|SOAP]] protocol and [[Web Services Description Language|WSDL]] bindings. There has also been considerable work and progress in defining [[Representational State Transfer|Representational State Transfer]] web services..
