  • Controlled VocabsLiterally - A list of terms to choose from

    Aim is to promote the use of common vocabularies so it makes it easier to transfer data between different parties

    Promoting use of vocabs in specific themes via data guidelines and deriving new vocabs where required

    Vocabs are available through 3rd parties or alternatively served using the NERC vocab server developed in coordination with the european project SeaDataNet.

  • MEDIN Data Guidelines

  • Data GuidelinesDocuments with tables and Excel versions of tables which are organised on a thematic basis which consider the actual data

    Instill good practice amongst usersAllow contracting organisations to specify a format that data should be returned in thatcan be readily used and includes all relevant attributesProvide a consistent format for contractors to work to (rather than a different format for each contract)Allow easy ingestion of data to Data Archiving Centres Improve interoperability between organisations by providing a format which can be used to import and export data

  • Data GuidelinesSeabed geophysical surveys to be released in April.

  • Data Guidelines

  • Data Guideline StructureThe structure of the tables in the MEDIN Data Guidelines have been created to conform to many of the key concepts in marine data acquisition and management.

    For example the concepts of a project, sample methods (data production tools) and a sample event are very strong and can be mapped to most marine data.

    Each table refers to a specific component and some tables are common to all data guidelines. The tables are:

    *Project - a collection of surveys that have been completed for a common purpose*Survey - a uniquely identifiable programme of data collection such as a research cruise, moored instrument deployment or survey*Fixed Station a target location used as the basis for replicate sample events and for repeat monitoring surveysSample Event a sample specific event of data collection Sampling Methodology (Data Production Tools) Details of any method or instruments used to collect the dataSample Data the data

  • History of developmentInitial thoughts to keep the data guidelines at a technically simple level. No use of xml, schemas, databases. Document and Excel chosen as preferred formatDrafted first guideline Sediment sampling by grab or core for benthos then revised, revised until MEDIN Standards WG were happy and then extended to other themes.1 year ago 3 contracts let to use the data guidelines in real worldFeedback is now incorporated into new versions. New versions are available as a zip file which includes the full guideline (pdf) a read this first document and document on the structure and the excel template.Alignment with INSPIRE (O&M) and tooling to be central to 2012 developmentNew Data Guidelines developed by request of stakeholders and other drivers

  • All guidelines are reviewed internally and by the relevant Data Archive Centre before publicationWherever possible we have built upon existing standards. E.g. ICES guidelines

  • Relationship to Discovery MetadataThe MEDIN discovery metadata format is aimed at allowing the non-informed user to discover data sets and it is likely that one discovery data set record will contain a large range of data types that are in turn covered by a range of data guidelines. Some of the information which is collected at the Survey Level in a data guideline is also required to create a discovery metadata record. It is intended that the information collected at the Survey Information level is reused for creating a MEDIN discovery metadata record.

  • ExceptionsIf transferring historic data then some mandatory fields may be omittedIf there is a specific need for transferring data then users can customise the GuidelineThe guideline can be extended to suits specific requirements
