Open Source web platform for publishing and sharing data with impressive deployment history:

Metadata is often described as “data about data”, or the who, what, where, and when.
In the geospatial world, for each dataset we maintain, we should record information about the data such as:
The Open Geospatial Consortium (OGC) OpenGIS Catalogue Service Implementation Specification, currently at version 2.0.2, is a standard for discovering and retrieving spatial data and metadata.
Catalogue Services for the Web (CSW) is the HTTP protocol binding of the Catalogue Service Implementation Specificaton that allows for publishing and searching of metadata.
The project is certified OGC Compliant, and is an OGC Reference Implementation
pycsw is an official OSGeo Project
ZOO is made of three parts:
The rasdaman query language, rasql, offers raster processing formulated through expressions over raster operations in the style of SQL.
Consider the following query: "The difference of red and green channel from all images from collection LandsatImages where somewhere in the red channel intensity exceeds 127"
select ls.red - ls.green from LandsatImages as ls where max_cells( ls.red ) > 127
The software components of PublicaMundi are deployed initially into 8 virtual clusters, with the provision of spinning up more virtual machines into each cluster if necessary.
PublicaMundi utilizes Ansible Playbooks in order to deploy software to the integration environment, starting from empty Debian 7 virtual machines, with only network and ssh root access being preconfigured from Synnefo
