• Workflows are the new rock and roll
• Machinery for coordinating the execution of (scientific) services and linking together (scientific) resources
• The era of Service Oriented Applications
• Repetitive and mundane boring stuff made easier

• Access to distributed and local resources
• Automation of data flow• Iteration over data sets• Interactive • Agile software development• Experimental protocols• Declarative mashups• But...
• Can be hard to build• Can “decay” as services change

• Paul writes workflows for identifying biological pathways implicated in resistance to Trypanosomiasis in cattle
• Paul meets Jo. Jo is investigating Whipworm in mouse.
• Jo reuses one of Paul’s workflow without change.
• Jo identifies the biological pathways involved in sex dependence in the mouse model, believed to be involved in the ability of mice to expel the parasite.
• Previously a manual two year study by Jo had failed to do this.

The hidden costs of linked data
• Usability– We had a perfectly good scheme before and now
we change it for something more complicated!
• Performance– All those 303s!– Rumoured that on some sites developers
append .xml to save round trips

•Replayable – go back and see what happened•Repeatable – run the experiment again•Reproducible – independent expt to reproduce•Reusable – use as part of new experiments•Repurposeable – reuse the pieces in new expt•Reliable – robust under automation•Referenceable – citable and traceable

Stereotypes
• Publication Object– Record of Activity– Credit/attribution
• Live Object– RO as work in progress– Up to date references to
appropriate resource• Archived Object
– RO as a record of what happened
– Curated, “fossilised”, immutable aggregation
• View Object– Named Graphs for LD
• Exposing Object– Standardised wrapper
around data sources• Method Object
– RO as protocol

How Country is my Country?How Country is my Country?
A researcher explaining their “workflow”... 1) Use SPARQL to generate a collection of signal2) Publish that collection3) Our local signal repository has copies of the actual signal, and
publishes sub-graphs of linked data asserting what those signals are of (using the URI for that track/record etc.)
4) The workflow performing the feature extraction combines (2) and (3) when fetching the signal for feature extraction and classification, and persists the URI for the signal artefact (track/record etc.)
5) The results are published (e.g. of genre classification) and reference that URI

Evolution of our research environmentEvolution of our research environment
1st GenerationCurrent practices of early adoptors of tools.Characterised by researchers using tools within their particular problem area, with some re-use of tools, data and methods within the discipline. Traditional publishing is supplemented by publication of some digital artefacts like workflows and links to data. Provenance is recorded but not shared and re-used.Science is accelerated and practice beginning to shift to emphasise in silico work.
2nd GenerationProjects delivering now.Some institutional embedding.Key characteristic is re-use - of the increasing pool of tools, data and methods across areas/disciplines. Contain some freestanding, recombinant, reproducible research objects. Provenance analytics plays a role.New scientific practices are established and opportunities arise for completely new scientific investigations.Some expert curation.
3rd GenerationThe solutions we'll be delivering in 5 yearsCharacterised by global reuse of tools, data and methods across any discipline, and surfacing the right levels of complexity for the researcher. Routine use.Key characteristic is radical sharing .Research is significantly data driven - plundering the backlog of data, results and methods. Increasing automation and decision-support for the researcher - the VRE becomes assistive. Provenance assists design.Curation is autonomic and social.

Deluge of data => Deluge of methods to process it?
Recording, re-using and sharing methods: Supports reproducible science Enables interpretation & trust of results Supports re-use and re-purposing Shares know-how Builds capability to understand data
Methods should be first class citizens!

• How we share– We are co-evolving a social infrastructure for sharing
• What we share– In the future we’ll be saying “Could I have a copy of your
Research Object please?” (if we didn’t pick it up from the tweet...)
• Current work– Comunity curation, expert curation, assisted curation– Emerging practice in automation over linked data– Boundaries and guarantees: “the Web – particle duality”

• Linked Data community has guidelines and tooling for production
• Production practice will improve as consumption increases– e.g. Discovery– e.g. Versioning
• Issues of authority, licence, governance and curation are perhaps best addressed by the open repository community
• Balancing freshness with persistence
