The overall aim of the IGIBS project is to try and improve the relationship between the UK’s National Spatial Data Infrastructure (SDI) as manifested through the UK Location Programme (UKLP) and the UK’s academic SDI.

Our main objective is to focus on use cases emerging from research and education related to a particular area – the UNESCO designated Dyfi Biosphere Reserve.  Once articulated, these user requirements will drive the creation of two pieces of software of wider applicability and assist Aberystwyth University in developing resources for use by local students.

We are building on much prior art, especially in the area of Access Control.  EDINA runs the UK Access Management Federation (UKAMF) and, while it might not be fashionable, the reality is that many SDI resources, eg, data and web services, are going to stay protected.  This is true both of INSPIRE at the European scale and the UKLP nationally.  We aim to show how Shibboleth (the open source software that underpins the UKAMF) can be used to enable a wider range of use cases, so that UK students can get access to both open and protected resources, eg, from UK public authorities like Welsh Government.

We expect that the main four products resulting from this project will be:

  1. Working prototype of a “WMS factory” tool
  2. Simple mapping application
  3. Best Practice model for using UK academic SDI at the departmental level
  4. Demonstration of UK access management technology being used to secure public sector services in combination with academic sector services

SDI is underpinned by open geospatial standards like the OGC’s Web Map Service (WMS).  The “WMS factory” tool will allow users to upload their data and instantiate a WMS so that their data can then be viewed online, via a simple mapping application, in conjunction with reference data from Welsh Government.

Shibboleth is already used in academia, we extend its use here to demonstrate how public sector data can be made securely available to authenticated and authorised users within academia.

The Institute of Geography and Earth Sciences (IGES) has ambitions to improve the way it educates students in the use of open geospatial interoperability standards and intends using the Dyfi Biosphere Reserve area as an exemplar.  To this end we are conducting an inventory of data for the area and creating a repository for educational use.  The “Best Practice model for using UK academic SDI at the departmental level” will feed into this activity as well as provide guidance for the wider university sector.

This is a big topic that is often neglected and often proves fatal for SDI initiatives meeting their ambitions.  The reality is that much valuable data is restricted; this is true for the UK National SDI (UK Location Programme), the UK academic SDI and INSPIRE.  A genuinely interoperable means of allowing OGC Web Service clients (like the one we are developing in IGIBS) to consume WMS (open and restricted) from multiple distributed organisations without having to provide multiple user credentials is difficult.  Building on much prior work, we are going to try to demonstrate in IGIBS how Shibboleth – the open source SAML implementation that powers the UK Access Management Federation – can be used to allow protected public sector WMS can be made securely available to the academic sector.  We will also demonstrate the converse, how users in the academic sector can securely publish their data and control who can see it if they need to.  We will use this page to solicit comment and hopefully gather recommendations for further work.
