frameworkthatincorporatesjointly(a)theory,(b)conceptualdesignanddev- opment, and (c) applications, in particular case studies and industrial solutions. Following and expanding the model created in 2003, we again solicited and selected quality workshop proposals to complement the more archival nature of the main conferences with research results in a number of selected and more avant garde areas related to the general topic of distributed computing. For instance,theso-calledSemanticWebhasgivenrisetoseveralnovelresearchareas combining linguistics, informationsystems technology,andarti?cialintelligence, such as the modeling of (legal) regulatory systems and the ubiquitous nature of their usage. We were glad to see that no less than eight of our earlier successful workshops(notably AweSOMe,CAMS, SWWS, ORM,OnToContent,MONET, PerSys,RDDS) re-appearedin2007withasecondorthirdedition,andthatfour brand-new workshops emerged to be selected and hosted, and were successfully organized by their respective proposers: NDKM, PIPE, PPN, and SSWS. We know that as before, workshop audiences will productively mingle with another and with those of the main conferences, as is already visible from the overlap in authors! The OTM organizers are especially grateful for the leadership and competence of Pilar Herrero in managing this complex process into a success for thefourthyearinarow. A special mention for 2007 is to be made of the third and enlarged edition of theOnTheMoveAcademy(formerlycalledDoctoralConsortiumWorkshop),our vision for the future in research in the areas covered by OTM.
