Web information systems are in a point where certain technologies and practices have reached a mature level of development and adoption by the industry. These information systems are widespread on institutions with different contexts and scopes, but in a global world these systems have the interoperation needs through standards that define ways to distribute high quality contents or services. On the other hand, there is an increasing number of new web technologies, tools and kinds of contents, devices and services that thrive outside of the world of institutions. This needs to be combined with new models of distributing, delivering and accessing to services: Open Resources, Open Source Software and Creative Commons Licenses, and even the freemium business model that companies like Google, Layers, Prezzi or Twitter have a deep impact in the panorama of Internet services. This special issue is devoted to the problem of how to integrate service based tools and contents, mobile applications and cloud computing services into the legacy systems. Systems that institutions have been implementing and putting to use with a loss of effort and internal transformation; and that now realize that their systems are limited, closed and far away to the crest of the wave on systems innovation. This is a problem that seems to have a solution in the domain of Service Sciences, both from a technical point of view of SOA and interoperability standards, and from a point of view of business models, ways of collaboration inside software development teams and fair licensing strategies. This special issue includes experiences and perspectives organized in 9 papers
