https://rd-alliance.org/ - https://twitter.com/resdatall IG Data Fabric Status – working on: Delivering harmonized recommendation doc (GDOC + virtual layer paper) as supporting output editing, discussion, heading for submission after P10 https://rd-alliance.org/ - https://twitter.com/resdatall

Data Fabric components Consensus on essential consensus – but detail questions remain: Is the scope of each component well-defined? How do the components interact? What combinations of components make sense? What is typical use?  Systematic study on components and their networked sets scope, role, interfaces, status of interface specs, status of implementation, relation with layers, governance issues also: what does layering mean for implementations scenarios and disciplines? https://rd-alliance.org/ - https://twitter.com/resdatall

WG Research Data Collections (Research) data management beyond single objects Not just describe collections, but enable actions on them Create, Read, Update, Delete, List plus some others Machine agents as primary users Contribute an essential component to the Data Fabric Provide a cornerstone API specification against which tools and services can be built across community boundaries

Design considerations Key requirements: Favor limited functionality over support for use case details Offer extension points Use by machine agents primarily No constraints on particular back-ends No mandatory use of PIDs (supported, but optional)

API: Structure

Current implementations and use cases REPTOR: data repository, also covering DTR and DFT recommendations Tufts: Python/Flask implementation for Perseids Project backends for file system, RDF/LDP, MongoDB iDigBio: Python and redis-based Use cases: Perseids, iDigBio, GEOFON, DKRZ/CMIP6, CAU Kiel/IGSN – more are welcome! Full recommendation document in editing over summer! https://rd-alliance.org/ - https://twitter.com/resdatall
