Their creation is supported by a complex ecosystem of i) data providers who offer open APIs to users, ii) users who combine APIs into mashups, and iii) platforms, such as the ProgrammableWeb or Mashape, that facilitate the construction and publication of mashups. In this article, we argue that the evolution of the mashup ecosystem can be explained in terms of ecosystem niches anchored around hub or keystone APIs. The members of a niche are focused on an area of specialization (e.g., mapping applications) and contribute their knowledge to the value proposition of the ecosystem as a whole. To demonstrate the formation of niches in the mashup ecosystem, we model groups of related mashups as species, and we reconstruct the evolution of mashup species through phylogenetic analysis.  10aecosystems10aevolution10agrowth10akeystones10amashups10aniche formation10arecombinant innovation10aspeciation1 aWeiss, Michael1 aSari, Solange1 aNoori, Nadia  uhttp://timreview.ca/article/68301697nas a2200241   4500008004100000022001400041245007300055210006900128260004200197300001000239490000600249520097000255653003001225653002101255653001401276653002601290653001601316653003701332653001701369653001001386100002301396856003601419       2012                        eng d  a1927-032100aGovernance of Open Source Software Foundations: Who Holds the Power?0 aGovernance of Open Source Software Foundations Who Holds the Pow  aOttawabTalent First Networkc12/2012  a37-420 v23 aThe research reported in this article attempts to discover who holds the power in open source software foundations through the analysis of governance documents. Artificial neural network analysis is used to analyse the content of the bylaws of six open source foundations (Apache, Eclipse, GNOME, Plone, Python, and SPI) for the purpose of identifying power structures. Results of the research suggest that: i) the actions of an open source software foundation are centered around one of three groups: Members, Chairman/President/Executive Director, and Board of Directors; ii) in only one of the six foundations is the Board of Directors responsible for both the community and the product; and iii) artificial neural network analysis of the content of bylaws provides unbiased insights of the power structure of open source software foundations. These results may prove useful to those who contribute to open source foundations and use their products and services.10aartificial neural network10acontent analysis10akeystones10amanagement structures10aopen source10aopen source software foundations10aorganization10apower1 aPrattico, Ludovico  uhttp://timreview.ca/article/636
