[Medin_standards] New Discovery Metadata Guidence Document

[Charlesworth, Mark E.]

All,
The MEDIN discovery metadata guidance document (2.3.4) is available at  http://www.oceannet.org/marine_data_standards/medin_approved_standards/documents/medin_schema_doc_2_3_4_30nov2010.pdf
The changes will filter down to the tools in due course.

We have also revamped the oceannet website (www.oceannet.org<http://www.oceannet.org>)  including the standards pages - any comments back to me please.

Lastly, Becky has provided a draft definition of what a 'service' is  - see below - any comments back to Becky at bese at MBA.ac.uk<mailto:bese at MBA.ac.uk>
Best Wishes
Mark



Services

MEDIN considers a service to be a web service (specifically an implementation of a geo-portal software architecture), that provides access to geographic and thematic information in marine data;

A discovery service - Allows the discovery of data set(s) via the searching of metadata records.

A view service - Allows the viewing of data set(s) or parts of data set(s) via a map interface.

A download service - gives access to data set(s) or a part of data set(s). The
Download Service provides access to spatial objects whether representing discrete or continuous phenomena.

A transformation service - a service for carrying out data content transformations. This is an auxiliary service type normally connected with a download service. It is designed as a mechanism to enable spatial data sets to be transformed with a view to achieving interoperability. An examples would be transforming between coordinate reference systems.  A transformation service will usually not be made directly accessible for the general public but a metadata record of it should exist.

An invoke spatial data service - A service invoking the use of other spatial data services that allows the definition of data inputs and data outputs expected by the spatial service and defines a workflow or service chain combining multiple services. It also allows the definition of a web service interface managing and accessing (executing) workflows or service chains.
