	On 28th August 2000 Brian McBride a researcher at HP Labs Bristol in the UK announced the JENA project with a brief [http://lists.w3.org/Archives/Public/www-rdf-interest/2000Aug/0128.html message to the W3C RDF Interest Group mailing-list]. His hope was to build “better tools {that} will help to encourage the adoption of RDF”. Though calling for an Apache project for the Semantic Web for some time little did Brian know that 20 years on Jena would be known as a top level Apache Jena Project with a strong and steady community developer base with almost half a ~~millions~~ lines of code in the release. Today JENA consists of a RDF API, a triple store called TDB a RDF storage solutions and the OWL API. And last but not least a fully fledged SPARQL server called FUSEKI. It shows that Jena is now more than just a Java API to process RDF. It is shaping technology standards and did help the wider Semantic Web community by advancing technology tools to bring the Semantic Web vision to its full potential. The evolution of the Jena project is described loosely along four distinct phases of the projects life cycle: An innovation phase that bootstraps the project, an early adoption phase that comes as a result of availability of a usable code base, followed by a late adoption phase that evolved along a more stable release cycle and new product features and design patterns. Finally we take a look at the most recent phase that is associated with attempts to mainstream the technology and can be described by a prolonged phase of adoption in the mainstream.

	'''Apache Jena''' is an open source Semantic Web framework for Java. It was initially produced by HP Labs (until October 2009) in Bristol UK, and after a brief period as openjena it became an Apache Software Foundation project. Jena provides an API to extract data from and write to Resource Description Framework (RDF) graphs also called a Model in Jena. A model can be sourced with data from files, databases, URLs or a combination of these. A Model can be queried through a query language such as SPARQL 1.1 and specific ARQ extensions. The framework has various internal reasoners can be set up to work with different OWL and rules profiles.		'''Apache Jena''' is an open-source Semantic Web framework for Java.
