Re: [teiid-dev] About your post on "Semenatic Web"issues

Hello Sebastian I share your concerns, even though (or precisely because) I'm not a 'referent' in Application and Data storage interoperability, I'm a seasoned SW engineer (1). My feedback on your article, is that the use case illustrates the challenges and needs for a web of interoperables solutions (maybe you could mention SKOS among the Semweb languages) My interest for interoperability started in 1997, at this time there was CORBA and Microsoft COM, then regarding RDBMS, there was ODBC/JDBC. There was also all the vendors buzz like SAP pretending to teach esperanto to the babel towers of legacy apps (but in fact replacing backoffice apps by theirs) Some time XML and its modelling 'applications' (XML Schema and XMI) gave me some hopes, but still no concrete sign of 'user driven apps' built by a dynamic process of looking for and assembling 'autodescribed components' (SOAP and WSDL was then a kind of CORBA successor) Before the Semantic Web, I had never really 'bought' the idea that SQL based Data Storage was considered as a 'Silver Bullet', ORM solutions seemed to bring even more entropy. But with the advent of Graph Databases (e.g. Neo4J) and this brilliant solution (Apache MetaModel) for Data Storage interoperability, I am at last more comfortable and comfortable with the idea that the solutions are available for designing interoperable solutions in an elegant way at last. I am most fluent in the DataViz and ETL dimensions of Semantic networks. I authored a mindmapping app in 2004: Thinkgraph, now I'm prototyping a solution to provide interoperability between 'knowledge visualization' (e.g. TheBrain, XMind), Data Storage and Curating platforms (e.g. Pinterest, Evernote, Youtube, etc..). I chose .Net/C# as my development workshop thats why I started a port of Apache MetaModel in C#. Best Regards Michel Kern 1. Dassault Systèmes 1991-2000, Nokia 2001-2010
