Q: What is Metadata?
A: Metadata is information about data. Metadata records document the who, what, when, where, how, and why of a data resource. Geospatial metadata describes maps, Geographic Information Systems (GIS) files, imagery, and other location-based data resources. As an analogy- imagine lots of tins of food without labels. How do you know what's in it, what the best before date is, who made it, and whether it's fit to eat?
Q: What is INSPIRE?
A: The INSPIRE Directive aims to create a European Union spatial data infrastructure for the purposes of EU environmental policies and policies or activities which may have an impact on the environment. This European Spatial Data Infrastructure will came into force in 2009 and aims to enable the sharing of environmental spatial information data among public sector organisations, and facilitate better public access to the same data. The UK Government mandated that all local authorities publish spatial information across Europe and assist in policy-making across boundaries.data under the INSPIRE framework, for particular "themes", and with three phases:
- Make data discoverable by creating INSPIRE-compliant metadata and publishing through a data discovery service. In the UK this means using the Gemini 2.2 metadata standard and publishing through data.gov.uk
- Publish data through INSPIRE-compliant web services to allow the viewing and downloading of data. In general this means using a Web Map Service (WMS) for viewing and a Web Feature Service (WFS) for downloading.
- Transform data to comply with INSPIRE data specifications. In the UK this phase has not yet been enacted.
See the attached pdf "A guide to INSPIRE compliance in local government" for further information.
Q: What is Gemini?
A: Gemini is the UK implementation of the INSPIRE metadata standard. It describes the information that is required for a metadata record to be compliant with INSPIRE and to be accepted for publication to data.gov.uk. The current version of Gemini (as of October 2018) is 2.2, but by December 2019 records will need to be compliant with Gemini 2.3. For more information about Gemini please visit the official documentation at https://www.agi.org.uk/agi-groups/standards-committee/uk-gemini
Q: What is 'Get INSPIREd'?
A: Get INSPIREd is an initiative by Astun Technology to get allow existing and new and existing customers alike customers to create metadata that is compliant with the INSPIRE directive from the EU in an easy to understand and cost effective work package, which can be added to an iShare roll-out or delivered independently. framework, ready for publication to data.gov.uk. It is a cost-effective and easy to use implementation that can be integrated with existing workflows or be completely stand-alone.
Q: What is a Metadata
...
Catalog?
A: A metadata catalog, or store, or portal, is where metadata records are held and ordered. The data that the records refer to is held elsewhere, such as in a database. The catalog provides a searchable access point for your metadata, and a service endpoint (CSW) that can be used by external parties (such as data.gov.uk) to ingest or harvest your metadata.
Q: What is GeoNetwork?
A: GeoNetwork is an the leading open source metadata storecatalog. Astun Technology use GeoNetwork as the basis for the GetINSPIREd initiative and are committed to maintaining the plugins to use Gemini 2.2 (and soon 2.3) in GeoNetwork.

iShareGIS?
A: Metadata records stored in a metadata store can be accessed in iShare by linking metadata records to their corresponding layer in iShareA layer in iShareGIS can be linked to it's corresponding metadata record in iShare Studio. Please see Metadata Overview for the information on the initial configuration of iShare Studio to link it to GeoNetwork, and then the method for linking metadata to a layer. Once the metadata is linked, then it is available for viewing via the "omnisearch" bar in iShareGIS, or via the controls for an individual layer.
Q: Are any metadata records stored in iShare?
A: No metadata is stored in iShare, just links to the records, so any updates made to the metadata store will be reflected in the metadata available in iShare.
Q: What is a CSW Interface?
A: A Catalogue Service for the Web (CSW) is a web service, much like a WFS or WMS, but is used to access Metadata records rather than Spatial data and is the method by which external parties such as data.gov.uk gain access to the metadata. Only metadata that has been published can be accessed by the CSW service.
Q: How do I configure Studio ETL to access my CSW Interface?
A: There are two steps involved in this process, the first is to configure the WebStudio and MetadataWebService URLs, the second in configuring your CSW end-point.
The first step is done in iShare settings under the 'Master Settings' tab, scroll down to the sub-heading titled 'WebService' and make sure that you have the MetadataWebServiceURL and WebStudioURL configured.
The second step is also found in iShare Master Settings under the sub-heading titled 'Catalogue Service for the Web' where the end-point of your CSW can be entered.
See examples below:
Q: To access metadata in iShare, what format do my Metadata records need to be in?
A: The Metadata records in the Metadata store will need to be in UK Gemini 2.2 format. These records need to correspond to the layers in iShare in order to link through correctly.
Q: How do I access Metadata in iShare?
A: To do this you will need to associate Metadata records with their corresponding iShare Layer. The Metadata for each layer is not accessible in iShare until these layers have been linked to the Metadata.
The best way to do this is to perform a search in Studio for metadata records that correspond to the layers contained in iShare. In Studio, you will need to navigate through the following nested folders; under 'Map Sources' expand the 'My Maps' sub-heading to reveal the 'Metadata' node.
Clicking on the 'Metadata' node will reveal a list of Map Sources for My Maps. Each Map Source will contain Layer Groups, containing Layers. Each Layer will display one of two options depending on whether they have or do not have a Metadata record attached to them.
Layers that have no Metadata record will simply give the option to 'Find', this will open a search box to help navigate to the correct Metadata record for that particular Layer.
Layers that have a Metadata record will give the option to 'Remove' or 'Replace' that record where 'Remove' will un-link the record, and 'Replace' will un-link the existing record and link the new record again utilising the search box to navigate to the desired record.
Q: What is the advantage of linking Metadata records to Layers in iShare?
A: You will be able to display the Metadata record for a given Layer in both iShare Maps and iShare GIS, and Search for Metadata records in iShare GIS.
