THEME:


Nowadays businesses as well as the Web require information to be available in real-time in order to reply to requests, make effective decisions and generally remain competitive.
This in turn requires data to be processed in real-time. In general in service-oriented architecture (SOA) one is less concerned with latency in data processing. Clearly, there are investigations of service-level agreements (SLA) and quality of service (QoS) to guarantee service delivery. Research around non-functional properties and service-level agreements for service-oriented computing has reached a level of maturity. There are approaches for describing properties, managing SLAs and even for selecting and composing services based on NFPs.
Beyond these classical topics SOA inspired extensions are enabling new and creative domains like the Internet of Things, real-time business or real-time Web. These new domains impose new requirements on SOA, such as a huge data volume, mediation between various data structures and a large number of sources that need to be procured, processed and provided.
Questions like how to pick the right service out of tens of thousands of services if we talk about sensor networks or how to provide results with almost near zero-latency describe actual questions and challenges we are currently facing. Therefore, we have to look into new ways for processing data, converting and composing data coming from various sources and for enabling an easy and lightweight way to impose it on various sets of devices.

This is further motivated by the recent evolution of the Web, which is changing radically the way data and services are shared, used, and combined. On the one hand, impelled by Web 2.0 technologies, services on the Web are increasingly shared openly based on REST principles and a light technology stack based largely on HTTP and XML or JSON. On the other hand, there is an ever increasing amount of data available on the Web provided by RESTful services, social networks, open data initiatives, and even sensors. To cater for this increase in the quantity
of data but also in the diversification of its nature, Linked Data principles are emerging as the best means for sharing data on the Web by exposing and interlinking information about any entity on the basis of URIs and RDF. These technologies are giving birth to a Web of Data about basically anything. Driven by the aforementioned trends, the emergence of a Web of Services capturing data about services and their relationship with other services and real-world entities such as people, organisations or products is gradually taking place, see for
examples initiatives like GoodRelations and iServe. Finding, composing, invoking and enacting services effectively in this new context is thus increasingly becoming a matter of efficiently and effectively analysing and combining large amounts of data to make informed and adaptive decisions.

The first four editions of the NFPSLA-SOC Workshop were organized at the ICSOC 2007, ECOWS 2008, ICSOC 2009 and ECOWS 2010. They were focused on the management of Non-Functional Properties and Service Level Agreements in the context of Service Oriented Computing. While the general objectives of the workshop remain the same, for the current edition of the workshop we aim to create a forum where one can expose and discuss novel ideas on the use and management of on-functional properties and Service Level Agreements bearing in mind the aforementioned evolution in service technologies and related activities influencing the service world such as social networks, open data initiatives, and even sensors. The workshop aims to tackle the research problems around methods, concepts, models, languages and approaches for management, including finding, composing, invoking and enacting services informed by non-functional properties as well as by any other information related to services. This proposed workshop aims to bring together researchers and industry attendees addressing these issues, to promote and foster a greater understanding of how the management of NFP, QoS and SLAs can assist business to business and enterprise application integration. We are especially interested in new ways utilizing linked data, Web2.0 approaches to enable scalable service related tasks based on non-functional properties and SLA descriptions.
