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 is the dataset’s study area?
When were the data collected?
Why was this dataset created?
type of application?
spatial reference system?
processes or algorithms used?
Who created the dataset?
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?
The importance of geospatial metadata
Local Data Management

Geoportal : an interface to run searches on the internet and local catalogues to locate geographical resources, and to discover metadata records representing spatial data and geo services.
Geoportal Metadata Record Spatial Datasets and Geo-services Spatial Data Discovery via a Geoportal
A geoportal enables users to search and discover spatial data via metadata using free text , resource type , geographic location (co-ordinate and placename) and date .
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 standards are critical for supporting metadata creation and…………………………

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 element set of a standard to support interoperability across the wider geospatial community ( Discovery level metadata). * Perhaps include 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.
These data and services to be delivered through initiatives across Europe.
INSPIRE Regulations 2009 No 3157 came into force on 31 December 2009 and applies to England, Northern Ireland and Wales.
Scotland’s Parliament enacted a complementary regulation which came into force on the same date.
Public authorities will be obliged to produce and keep up to date ‘metadata’ for describing datasets, dataset series and geo services.
Includes UK academia as it must comply with the 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 state 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).

INSPIRE Metadata Editor tool and Geoportal
* 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 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 conform to 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 Go-Geo! 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.
