1. An introduction to MEDIN Data Guidelines

2. What MEDIN data guidelines are not… Protocols for collection methods Prescriptive of how you have to collect and store your data Metadata schema MEDIN guidelines are Data Archive Standards: They provide a list of information that should be collected with your data to ensure they can be re-used in the future.

3. Data guidelines Instill good practice amongst users Allow contracting organizations to specify a format that data should be returned in that can be readily used and includes all relevant attributes Provide 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

4. Relationship to Discovery Metadata MEDIN discovery metadata – allows the non-informed user to discover data. MEDIN data guidelines - all the information that will make your data re- useable

5. 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 themed by method and split into levels Where possible levels work across methods These standard kits can be bolted together in different ways if needed for complex surveys (e.g. where collecting data using different methods in a single survey)

6. Data Guideline Structure 3 requirements: General Metadata Project Survey Detailed Metadata Methods Data Station Sample Event Sample Data Common to all guidelines Specific to each guideline

There are 3 requirements to ensure that your benthic data using a grab or core are MEDIN compliant: 1.You supply General Metadata about your data – See Appendix A 2.You supply Detailed Metadata about your data – This may be included in a survey/cruise report or as additional metadata – See Appendix B 3.Your data are in a format that MEDIN accepts – See Appendix C Introduction 1.1 What are MEDIN compliant data?

16. Practical Aim – to familiarise yourselves with the structure and content of a Data Guideline. 1)Find the Data Guidelines page on the MEDIN website. Which data guidelines look relevant to your work? Is there an obvious gap for your work? 2)Open the Data Guideline for species and benthos data collected by dredge or trawl surveys from your desktop (the pdf) 3)Start to fill in the data guideline as if you were on survey
