Learn why we need MEDIN guidelines to capture essential knowledge and ensure reuse of marine data. Understand the best practices and benefits of following these guidelines for archiving and ingestion at Data Archiving Centers.

Re-using data- MEDIN Data Guidelines Roseanna Wright (acknowledgements to Mary Mowat, BGS)
Why do we need MEDIN guidelines? data data • MEDIN know from bitter experience that, as time passes, assumed and unrecorded knowledge about the data gets lost • Without this knowledge, the data may not be easily re-used or cannot be re-used at all! • MEDIN Guidelines provide a framework for capturing the assumed and otherwise potentially unrecorded knowledge necessary to re-use marine data data MEDIN GUIDELINES
What MEDIN data guidelines are… • They are best practice guides on archiving marine data: • They provide a list of information that should be collected with your data to ensure they can be re-used in the future. • What MEDIN data guidelines are not… • Protocols for collection methods • Prescriptive of how you have to collect and store your data • Metadata schema
Benefits of Data guidelines • Allow knowledge to be captured at time of data collection or immediately afterwards • Instill good practice amongst users • Good for contracting organizations and contractors – standard format to work to (rather than a different format for each contract) • Allow easy ingestion of data to Data Archiving Centres
One size does not fit all • Our data model has to encompass everything from a sighting by a member of the public to a complex cruise survey or a historical time series! • Guidelines are arranged by theme, tailored to different data collection methods and split into levels • Where possible levels work across methods • Theming and splitting allows guidelines to be ‘bolted’ together in different ways if needed for complex surveys (e.g. where collecting data using different methods in a single survey)
Data Guideline Structure 3 levels: General Metadata Project Survey Detailed Metadata Methods Data Station Sample Event Sample Data Common to all guidelines Specific to each guideline

Data Files • Data should be beQC’d before submission • Contact DAC if data not in a standard format • Raw and processed data accepted if clearly specified/useful • Don’t include duplicate/draft files - Ensure data is in final form • Data should be well organised – Standard folder structure • GIS/shape files can be included (M Mowat, BGS, Nov 2016)
Summary MEDIN Data Guidelines • Best practice guides on archiving marine data • Data + Metadata • Flexible - Bolt Together • Collect Once – Use Many Times!
Guideline practical • Choose one example MEDIN dataset from options in next slide • Go to Data Guidelines page on the MEDIN website • Locate appropriate Guideline(s) for the data and download • Perform a checking exercise with the data • do you have all mandatory information? • What about the conditional and optional? • Are the data formatted for MEDIN compliance? • Try and complete a guideline using the selected data
