  4. 4. Summary of Innovations assisting the growth of the Greek Internet  2004 – Introduction in Greece of the first Google Ads in order to help smaller publishers to make money from their content. Trial was performed at where we helped Google debug its engine to support Greek and UTF-encoded text.  2005 - First deployment of Microsoft CRM for a greek NGO (Olympiacos); that became a Microsoft EMEA case study (see other presentation in my slideshare profile)  2007 - Established metadata with the encouragement and a loan from my former employer.  What “metadata” are, was unknown for most, though metadata became a household term in 2013.  Started with 5 people and did a turn-over of 300,000 on its first year - Grew to 18 people (and an 850,000 turnover on tis second year) and Reached nearly 30 people (and was looking forward to a multimillion turn over) was “killed” by such an event.  Indicative innovation. Our CMS, metaCMS succeeded in replacing one of the most expensive CMS on the market (Vignette) for Eleutheros Typos at a fraction of the cost, offering equal or better functionality. Vignette; it usually costs 300,000 for the setup and the first year and 150,000 annual maintenance fee.

  21. 21. metaCMS foundamentals  Ease of use  Easy Parametrisation  Extensibility  Security  Performance
  22. 22. metaCMS technology  Technologies utilized (dev stated in 2008).  .Net Framework 3.5 SP1  Linq to SQL  Generics  Lambda expressions  Ajax Extensions
  23. 23. Architecture  Treating news-stories as products for sale (with add-ons on various platforms) and retail products as rich-media objects (to differentiate them from competition)  Separating content from presentation  Web authorsweb developers can operate independently from designers.  The content can be transferred into different formats.  The content can be reused.  The complete redesign of the experience it is a matter of content managers and designer – no developers involved.
  24. 24. Architecture
  25. 25. Architecture  Architectural Design Fundamental Units  Templates The template has available regions-positions for the placement of specific controls with fixed or linked (with other control) dynamic content  Business Objects (content) Support for a series of content ontologies such as Articles, Files, Events, Banners whereas the open and modular architecture of the platform enables the creation of unlimited number of ontologies based on the requirement of the clients. Object update (debugging) can propagate to all clients.
  26. 26. Architecture  Controls Lists, Full Article, Custom controls  Modules Small autonomous applications that can be positioned in a page in the website. Support of modules such as Weather, Stock-market, Geo-Mapping  Services Search, Logging, Caching, Auditing, Versioning

  28. 28. Features  Error Logging  In the database, Flat files, andor Email alerts  Caching  Hierarchical, multi-layered categorizations of the ontologies  Dynamic change of Template  Dynamic change of Styles  Dynamic production of pages
  29. 29. Features  Dynamic page setup  Dynamic Resize and cropping of images with multiple versions for re-use of the same photo in different contexts (frontcategory page, full-article)  Every ontology can be recorded as RSS Feed  Every ontology can accept user comments  Every ontology can be Rated  In every ontology (inclusive of categories) polls can be added
  30. 30. Features  Ability to create ontological collections  Media Gallery for multiple file formats.  Mechanism to categorise, add Metadata, and search archives.  Creation of re-usable controls for the Back-office.  Role based user rights management per resource.  System parametrization infrastructure.

  37. 37. Sample code…  The C# sample code provided from the stock market module of metaCMS is indicative of the code writtensupervised.  The _css, _js and _gfx directories provided by one of the Sklavenitis sites are indicative of the quality of the front-end code – part of it was part the given questionnaire (e.g. sprites, see wood_spirte.jpg).
  38. 38. Data Visualisation  The task at hand: Quantify the impact of the assets of one of Greece’s wealthiest individuals – personal property estimated to over $5 billion, map all the relations of his holdings in “one page”!  The solution: Collect data using WSS (the freeware SharePoint) through an InfoPath form. The XML feeds an SQL server (thus avoiding duplicate entries)  Following data cleansing a flat array was given fed into a Flash application (the demo you will see contains all the visual data in 66kb)  Year of development: 2005
