The key features of self-organizing coordination are also introduced and described and a series of examples of systems relying on self-organizing coordination approaches presented.

9		-(% style="border-style:hidden solid solid hidden; border-color:$theme.borderColor" %)!!We believe this paper is currently the one which most clearly states the requirements and objectives of pervasive service ecosystems. It also sketches a chemical-inspired approach to eco-laws construction, where chemical concentration is used to manage a service "activity value", promoting some ecological patterns of behaviour.

12		-#pubATVblock("ChemcoordSoarbook")
13		-This paper motivates the use of a model of chemical tuple spaces for the coordination of situated, adaptive, and diversity-accommodating pervasive systems.
14		-Moreover it is outlined a incarnation of that model on the TuCSoN coordination infrastructure, which can be suitably enhanced with modules supporting
15		-semantic coordination and execution engine for chemical-inspired coordination laws.

	7	+This page is intended to provide a view of the research work underlying SAPERE afforded by the APICe group.

18		-#pubATVblock("BiochemicaltuplespaceSac10")
19		-This paper introduces a model of service self-composition based on the use of ecological laws, which are specified by relying on the biochemical tuple space model. The paper shows how service lifetime can be completely managed in a self-organizing way as regards both survival/extinction and composition with other services.

22		-#pubATVblock("SemCoordSac2010")
23		-This paper show how to empower a tuple space model with semantic techniques by equipping tuple spaces with the ontological description of the coordination
24		-domain and by describing tuples as domain individuals described in terms of the ontology.
25		-In particular, the paper shows how such a model is very useful to address distributed and open scenarios.
26		-The model was implemented in the coordination infrastructure TuCSoN.

29		-#pubATVblock("MorphoEngBook13")
30		-The paper presents a computational model for capturing scenarios of spatial self-organisation.
31		-In particular it deals with the spatial pattern of gene expression generated in multicellular organisms during morphogenesis.
32		-I believe it can be of interest in the description of a possible model able to reproduce such a complex phenomenon, in the results obtained with the model of a particular organism (Drosophila Melanogaster) and in the considerations proposed for the use of morphogenetic mechanisms in the generation of artificial systems with similar behaviour.

35		-#pubATVblock("SelforgcoordKer25years")
36		-Here we discuss the potential of coordination models and languages as the sources for the abstractions and the technologies around which complex computational systems ~-- like intelligent, knowledge-intensive, pervasive, self-organising systems ~-- can be designed and built.

39		-#pubATVblock("FuzzycoordSac11")
40		-The paper shows an extension of semantic tuple spaces with fuzzy techniques in order to also represent vague/fuzzy knowledge so often required by real-world application scenarios.
41		-In particular in this paper it is extended the model of Description Logic tuple spaces with fuzziness in order to support fuzzy semantic coordination.

44		-#pubATVblock("SpatialTaas11")
45		-This paper motivates the use of a model of chemical tuple spaces for the coordination of pervasive service ecosystems. A case study of adaptive pervasive displays is used to show patterns of service competition, and of creation of computational fields based on chemical diffusion.
