Metadata creation protects investments of time and cost dedicated to dataset creation and development; maintains an inventory of datasets to reduce time required to re-assess existing datasets for new and future applications; ensures integrity of existing and new datasets using metadata as a tracking mechanism to monitor changes and edits to datasets; reduces and minimises the disruptive effects of staff turnover; eliminates or reduces the risk of redundancy in dataset collection; saves against accidental deletion of dataset files.

INSPIRE Directive Metadata Guidelines Infrastructure for Spatial Information in the European Community (INSPIRE)*European Commission (EC) *European Environment Agency (EEA) *Representatives fromMember States (Mapping/GIS)
Targets electronic spatial data and services for environmental information. Aims to create a European Spatial Data Infrastructure (SDI) based on Member States’ infrastructures, to improve interoperability of spatial information. Data and services to be delivered through European initiatives. INSPIRE Regulations came into force on 31 December 2009 and applies to England, Northern Ireland and Wales. Scotland’s Parliament enacted a complementary regulation on the same date. Public authorities obliged to produce and keep ‘metadata’ current for describing datasets, dataset series and geo-services. Includes UK academia (Freedom of Information Act, 2000).

UK GEMINI* First released in 2004 to support creation of ISO 19115 and e-GMS compliant metadata - supersedes the National Geospatial Data Framework (NGDF)* Targeting the UK public sector* 2010: UK Location Programme (UKLP) revised UK GEMINI 2.1 to meet the requirements of the EU INSPIRE Directive. UK Location Programme (UKLP) is a pan-government collaborative initiative with the responsibility to develop and implement the INSPIRE Directive 2007/2/EC and the UK Location Strategy.

Publication on open or private (Group) nodes
1) create and validate record; 2) submit record for review; 3) metadata creator is contacted; and 4) record is published on the GoGeo portal.Photographic Images copyright: Jupiter Images 2006
A simple interface designed for UK academia to run queries todiscover metadata for spatial datasets, and to locate geographicresources.The portal enables searching by the use of various optionsincluding- free text- date- resource type- geographic location GoGeo rebuilt and redesigned.

Access to metadata records published on a Group node
a repository for you to store and manage your metadata thus savings in cost and time; use metadata to announce your data and applications; advertise (and sell?) your spatial datasets to other interested parties in academia and in the private and public sectors; metadata in the portal can be referenced and cited for project proposals; could be configured as an internal resource to access and share datasets.* Cambridge, Edinburgh, Kingston, Leeds, Leicester, Sheffield and Southampton universities have created and published +200 metadata records on GoGeo portal (global and private).
