Represents a documented and ordered summary of information that describes something, in this case, spatial data. Provides the What, Where, When and Why for a spatial dataset. Includes its Ownership and Contact (Who) details and Access and Use conditions. Metadata (data describing data)
What are the ingredients? Where were ingredients produced? Who sells the ingredients? What are the brewing steps? When does the fermentation process end? Photographic Images copyright: Jupiter Images 2006 Think of metadata as a recipe for making beer.
Think of metadata as food product labelling. What are the ingredients? What is the nutritional value? How many calories and how much fat? When is this product’s expiry date? Where was it produced? Who produced it?
Where are these datasets’ study areas?
When were the data collected?
Why were these datasets created?
type of application?
spatial reference system?
processes or algorithms used?
Who created these datasets?
Can you tell me from any of these files….. Now think of metadata as spatial data labelling.
What do these polygons represent? What attribute information is associated with these polygons?
What do these SOILCLASS values mean? What does this attribute mean?

Discovering spatial data through metadata offers the prospect of developing new applications
Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM) introduced in mid 1990s for documenting spatial datasets.
ISO 19115 Metadata Standard for Geographic Information was ratified in 2003 and supersedes FGDC.

Geospatial Metadata Application Profiles
ISO 19115 standard has too many elements (300+)
* An application profile is derived from a standard and represents a reduction of the number of entities and elements. * It should include the core (mandatory) element set of a standard to support interoperability across the wider geospatial community ( Discovery level metadata). * Perhaps include other elements for Descriptive level metadata? * A profile can be extended to include elements which are best suited for a working group’s specific applications. Example: The Biological Data Profile (BDP) An approved profile with additional elements to document biological information such as taxonomy , methodology and analytical tools . http://www.flickr.com/photos/f10n4/186861991/

INSPIRE Directive [2007 /2/ EC]
T argets 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).
• Provide metadata catalogues to reveal what information is available.
• Provide online data discovery , view , download and transformation (interoperability) services.
• Licensing arrangements to allow for information sharing, access and use in accordance with each State’s regulations.
• Set up e-commerce arrangements where charging is applicable.
• Introduce monitoring mechanisms to show that information is being made available.
• Introduce co-ordination mechanisms to ensure effective operation of the infrastructure.
Comply with the 34 spatial data specifications in three annexes
(reference geographies, environmental datasets).

UK GEMINI 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.
UK Location Metadata Editor and Catalogue built with UK GEMINI 2.1
UK Academic Geospatial Metadata Application Profile, Version 2.1 (UK AGMAP 2.1) UK AGMAP 2.1 created to support the specific needs of the UK H&FE communities. Comprises elements from ISO 19115, UK GEMINI 2.1 and INSPIRE. Supports documentation of a dataset, dataset series or geo service for the purpose of discovery and description. Mapped to Dublin Core, FGDC, INSPIRE, UK GEMINI 2.1 and DDI.

Why publish metadata on the GoGeo portal?
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.
A repository for deposit and extraction of spatial data.
Supports access to and sharing of spatial data.
Holds national and international spatial datasets
(raster, vector and tabular).
Key to delivering a Spatial Data Infrastructure (SDI) for the UK
academic GI community.
