Introduction

• pycsw is a OGC CSW server implementation written in Python.
• Open Source project released under the MIT license.
• Runs on all major platforms (Windows, Linux, Mac OS X)
• OSGeo Project since 11 March 2015

Introduction

• pycsw fully implements the OpenGIS Catalogue Service Implementation Specification [Catalogue Service for the Web]
• pycsw allows for the publishing and discovery of geospatial metadata

Introduction

The project is certified OGC Compliant, and is an OGC Reference Implementation

pycsw is an official OSGeo Project

Project History

Goals

• Lightweight and easy to setup: a standalone catalogue, no GUI or metadata editing front end, designed for the use case of exposing ready-to-go metadata (files or in existing DB) through a CSW interface
• Extensible: the ability to add metadata formats and mapping them to a common information model and core/additional queryables
• OGC compliant: always pass CITE tests

Features

• Harvesting support for WMS, WFS, WCS, WPS, WAF, CSW, SOS
• Implements ISO Metadata Application Profile 1.0.0
• Implements FGDC CSDGM Application Profile for CSW 2.0
• Implements INSPIRE Discovery Services 3.0
• Supports ISO, Dublin Core, DIF, FGDC and Atom metadata models
• Standalone of embedded deployment (CGI or WSGI)
• Transactional capabilities (CSW-T)
• Flexible repository configuration (SQLite, PostgreSQL, PostGIS, MySQL)
• Federated catalogue distributed searching

More features...

• Simple configuration
• Extensible plugin architecture (profiles, repositories/backends)
• Seamless integration with Python environments (e.g. GeoNode, Open Data Catalog)
• Integration with CKAN through ckanext-spatial and ckanext-publicamundi
