The NERC DataGrid (NDG) is an interoperability project which began in 2003 with a three year e-Science funded project: The NERC DataGrid, was continued in 2005 with a two year successor project (NDG2), and continued into 2008 under the auspices of the NERC Portals Project. The activity is currently (October 2008) funded under the auspices of NERC interim funding pending the establishment of a long term NERC national capability in interoperability.

This trac site was established as part of NDG2, and consists of currently active pages and activities, as well as obsolete pages. We are in the process of updating it, to clearly mark what is history, and what is current. The main function of these pages is to assist in project management and delivery, not to provide information to prospective users of NDG technologies. We will provide links from here (eventually) for those purposes.

Current NDG Activities

NDG3 also known as the NDG Medium Sized Initiative (NDG-MSI) began in October 2008 and will run til the end of March 2009.

Abstract: NDG3 is about enabling the reuse of data within and between NERC commmunities (but also the wider community of users of environmental data). The key components of the current activity are to 1) build a community within NERC who are working not only on serving their own discipline, but on interoperation between their respective disciplines, and 2) provide the key services needed by that community: data discovery and reliable data description terms via discovery and vocabulary services (and appropriate exemplar portals). To do these things we are delivering workshops, foucssing on community tools and methodologies, and further developing and deploying services which make it possible for the met/ocean community to both exploit their own data and interoperate with the wider community via new standards compliant software consistent with the community methodologies.

NDG3 covers the following key activities:

  • Capability: Developing a national capability for environmental information modelling (as a necessary condition for environmental interoperability).
  • Discovery: Improving the Discovery Service
  • Vocab: Improving the Vocabulary Service
  • Software:Improving and modularising the NDG software stack (for data services, data access and visualisation as well as information browsing).
  • MOLES: Further developing MOLES.
  • Security: Further developing and deploying the NDG security stack.
  • Community: Developing the NERC interoperability community under the NDG banner.
  • Roadmap: Developing a roadmap into the future which clearly delineates operational from R&D activities.
  • Management: Project pages, including the monthly newsletters.

The old frontpage for the NDG2 project is here.

NDG2 delivered a number of products, the key ones were:

  • CSML: The Climate Sciences Modelling Language. The historical project management pages are here, however CSML has been spun off as an open source project with a life of it's own. See the  new CSML website.
  • MOLES: The Metadata Objects for Linking Environmental Sciences. The historical project management pages are here. New MOLES activities are now discussed on the MOLES page.
  • The operational NERC Data Discovery service, running here.
  • The operational NERC Vocabulary service, running  here, described on a  BODC web page
  • The deployed NERC DataGrid (software running at BODC, BADC, PML and NOCS).
  • The NDG Security.
  • A python software stack which provided a CSML based Web Map Service and a CSML based web coverage service, as well as support for browsing MOLES documents, and visualising maps from the NDG WMS.
