The combination of these has lead to the concept of open APIs and mashups. Since late 2005, there has been a rapid proliferation of applications, referred to as mashups, that combine data and services provided by third parties through open APIs with data sources owned by users. Open APIs give users access to the data or services of an information technology platform. A well-known example is the Google Maps API, which generates maps for a given location, whose output can be combined with other data and services into mashups.

Combining services and data from multiple sources raises several issues related to intellectual rights in mashups. However, the concept of mashups is currently in a nascent stage, and service and data providers often underestimate the relevance of these issues. In this paper we give an overview of open API licensing and provide examples from current open APIs. We then briefly discuss licensing of open APIs.

Licensing is not limited to software. We can associate a license with any kind of asset that holds intellectual value, and can thus be turned into a source of revenue. Here, our interest is on information assets, which include software and software components, but also services, processes, and content. For instance, a song that a user downloads from iTunes is an information asset. So is a web service such as the Google Maps API (application programming interface).1 aGangadharan, G R1 aWeiss, Michael  uhttp://timreview.ca/article/10500385nas a2200121   4500008004100000022001400041245002300055210002300078260004200101520006400143100002100207856003500228       2007                        eng d  a1913-610200aSoftware Licensing0 aSoftware Licensing  aOttawabTalent First Networkc07/20073 aG.R.
