Signposting your information MEDIN Discovery Metadata

What is metadata & what should I do with it? Essentially, metadata is: Information about a dataset • When Discovery Metadata is: • Who Information used to describe datasets (or series or services) so • Where that a user can easily find them using a portal and determine the • What details of where they can be accessed • e. g. March 2017 BGS Dogger Bank A documented record of datasets managed within an geophysics survey organisation or an application Discovery Metadata contains: • What I' • Title • Ownership of record • Abstract • Temporal coverage • Geographic coverage • Access conditions • Location of dataset (amongst others)

What is a dataset? • The correct level for a dataset is a cruise, survey or a set of repeat observations with a common purpose • A dataset usually constitutes a specifically -funded piece of work • The dataset should be easily extractable from a database for a 3 rd party • Searchable using an online interface e. g. MEDIN portal

Discovery Metadata Standard MEDIN have developed a Discovery Metadata Standard to enable online discovery of datasets 3 components make up the Standard

Discovery Metadata Standard - Guidance Available on website Compliant with: • ISO 19115 (Geographic information – Metadata) • INSPIRE • UK GEMINI 2 • ISO 19139 schema set for encoding xml However, there is a shorter, simpler version available! Currently being updated!

Discovery Metadata Standard - Vocabs The MEDIN standard specifies use of certain vocabularies (term lists) to distinguish your record as ‘marine specific’ P 02

Discovery Metadata Standard - Tools http: //www. medin. org. uk/data-standards/medin-discovery-metadata -standard On-line metadata generation and editing tool Desktop tool. Can work in stand alone mode.

Validation is critical! ► ►Validation is carried out using the MEDIN schematron ►Ease of update – one change in multiple tools rather than separate bespoke changes for each tool ► Schematron scans the structure of the XML and the requirement levels and other rules of the MEDIN standard ► Schematron and guidance available at http: //www. medin. org. uk/data-standards/medin-discoverymetadata-standard ► This does not QC the content of the record – GIGO applies

Summary of dataset discovery • Correct level of granularity is essential • Discovery metadata designed for display on MEDIN portal. • MEDIN tools use XML to do this. • MEDIN guidance on website plus FAQs:

Updating the MEDIN discovery standard • Standards evolve! Therefore: • MEDIN has placed itself to be engaged in and contribute to any changes in national and international standards that could influence our own • MEDIN is represented by members of the MEDIN Standards Working Group on various groups linked to discovery metadata e. g. GEMINI Working Group, BSI • Sign up to the e-mail list to be kept up-to-date on changes

MEDIN discovery metadata in action • Log onto the MEDIN portal – http: //portal. oceannet. org/ – Look at the ‘quick links’ on the right hand side and click on the map icon. – Have a short play with the Data Discovery Portal to see how the discovery metadata gets used. – Does your organisation have records in the portal or are there data there you could use? – Practical to follow!
