British Library / JISC / UKOLN Workshop2 Overview 1.Mapping the business process: the intricate mix of humans and machines 2.Some thoughts about workflow 3.Social networks and service development 4.Summary: take home message
British Library / JISC / UKOLN Workshop3 What do we mean by business process???
British Library / JISC / UKOLN Workshop4 A business process is a collection of related structural activities that produce something of value to the organization, its stake holders or its customers. It is, for example, the process through which an organization realizes its services to its customers.
British Library / JISC / UKOLN Workshop5 The linkage of business process with value generation leads some practitioners to view business processes as the workflows which realize an organization's use cases. …..Workflows???
British Library / JISC / UKOLN Workshop6 Workflow at its simplest is the movement of documents and/or tasks through a work process. More specifically, workflow is the operational aspect of a work procedure: how tasks are structured, who performs them, what their relative order is, how they are synchronized, how information flows to support the tasks and how tasks are being tracked.
British Library / JISC / UKOLN Workshop7 Distinction can be made between "scientific" and "business" workflow paradigms. While the former is mostly concerned with throughput of data through various algorithms, applications and services, ….the latter concentrates on scheduling task executions, including dependencies which are not necessarily data-driven and may include human agents.

British Library / JISC / UKOLN Workshop10 OK - so in the context of our institutions …… (and digital libraries)….. what exactly do we mean by business process and workflow ???
British Library / JISC / UKOLN Workshop11 (Very simple) e-Research Cycle Formulate hypothesis / ideas, test, experiment, observe: data creation, collection & capture Adding value: Data linking, annotation, visualisation, simulation (New) knowledge extraction: data mining, modelling, analysis, synthesis e-Infrastructure Open access Collaboration Scholarly communications: data disclosure, publication, citation, discovery, re-use Data management storage & validation: description, deposit, self-archiving, preservation, certification Data processing This work is licensed under a Creative Commons License Attribution-ShareAlike 2.0Creative Commons License
British Library / JISC / UKOLN Workshop12 Gathering information about (e-)research Project StORe: Source-to-Output Repositories (Edinburgh) –primary data : research publications –Survey questionnaire RepoMMan: Repository Metadata and Management (Hull) –Survey questionnaire and interviews –Activity diagram
British Library / JISC / UKOLN Workshop13 JISC Digital Repository Programme DigiRep wiki http://www.ukoln.ac.uk/repositories/digirep/index/JISC_ Digital_Repository_Wiki
British Library / JISC / UKOLN Workshop14 Data capture R4L Repository for the Laboratory Project (JISC-funded) automated data capture from instrumentation, deposit of results (chemistry) at Univ. Southampton SMART TEA electronic Laboratory notebook + annotations R4L deposit scenario
British Library / JISC / UKOLN Workshop15 User scenario (…part of….) 1.Produce strategy for synthesis (=idea) 2.Submit plan to SmartTea system (incl. identifiers) 3.Retrieve and follow instructions (sub-workflow?) 4.Experimental synthesis metadata automatically recorded on instruments (Smart Lab) 5.Create record for synthesised sample (+ proposed chemical identifier) in R4L laboratory data management system 6.Run spectral analyses on sample capturing further analysis metadata (incl. time-stamp, analysis software version, researcher details etc.) 7.Save spectrum in native and common formats 8.Invoke R4L data capture service and deposit files + metadata in laboratory repository….

British Library / JISC / UKOLN Workshop22 But…. ….how should we be formalising workflows?
British Library / JISC / UKOLN Workshop23 Workflow systems & standards YAWL METEOR-S BPEL OpenWFE RADRunner BPSS (ebXML) PSL Geo-Opera JDF XLANG Taverna Kepler Pegasus Triana SPA ICENI BioOpera Wildfire BPML WS-CDL Is workflow standard an oxymoron?
British Library / JISC / UKOLN Workshop27 DL workflows : a complex picture Workflows for data capture, deposit, preservation, citation, discovery, mining &&…. Multiple workflows interacting together Workflows may call on each other, in a defined order Multiple workflows may use common services e.g. Assign (identifier) Require sequential or parallel execution, have dependencies, be time-limited, repetitive Have an owner (control) Include essential human interventions ? ? ?
British Library / JISC / UKOLN Workshop28 Workflow…the answers to Who? What? When? in a business process. A workflow is only as good as the business process beneath it. Margie Virdell, IBM developerWorks
British Library / JISC / UKOLN Workshop29 Some observations…. 1.We dont know enough about institutional business process: –Learning & teaching, research, admin, enterprise 2.How to analyse, express and model processes 3.What types of models? –At what levels of granularity: strategic (for a manager) vs detailed mathematical specifications (for a developer) 4.Which workflow tools & standards should we use? 5.Learn from e-Science projects 6.Which processes are best driven by machines and which by humans? 7.How do human-directed processes interact with machine-driven ones? 8.What are the digital library touch points in these processes?
British Library / JISC / UKOLN Workshop30 Service-oriented architectures for Digital Libraries Produce process models (DLF?) Experience of VRE projects Integrative Biology user scenarios Service typology (e-Framework?) Identify services: service definitions Service interactions: service patterns Orchestration of Web services Choreography of Web services Workflow interoperability…. (another oxymoron?)
