2. EKT: The National Documentation Centre 3. & . Internet Building anopensource based ,open standards , infrastructure for the large scale provisioning ofreusable open conten t
5. software ? 6. emerging requirements ?
7. in large scale, using open standards 8. and addressing emerging requirements 9. Content types and characteristics (I)
10. Cultural - Humanities repositories : from research papers to commented cultural artificats:pandektis.ekt.gr 11. Educational reference material :studies, books, multimedia courses, project outcomes, e.g.repository.edulll.gr 12. Digitised and/or born digital e-books :ebooks.serrelib.gr( pre-release ) 13. Library automation systems and OPACs: linking the digital with the physical realm,abekt.gr 14. Digital objects in general 15. Content types and characteristics (II)
Different requirements and emphasis in features implemented in comparison toWeb Content Management System s 17. Fast evolving landscape. Full range of features required:
18.
Interoperability protocols and interfaces:
21. An open content open source software stack No easy task to tackle the full rangeof theseissues, in a scalableand viable manner
Solution :best of breed open sourcesystems for the assembly of a fullyopen sourceopen content delivery software stack
22. High quality FLOSStools are available: pluggable and modular stack, do one thing but do it at world class FLOSS/Open Standards is the enabler forscalable, viable, large scale open content infrastructures . Just like the Internet no long term alternative to open standards/FLOSS seems to exist! 23. viewers and enhanced user experiences 24. novel reading devices 25. mashups and linked data 26. The open software stack components best of breed: open source, setting the standards pace, world class features, scalable and robust communities 27. Case studies
28. 3 case studies:
The e-OPAC alpha version of openABEKT
Public Library e-books repository pilot: the Serres Public Library pilot

36. The interoperability layer between the physical and the digital library 37. Richer metadata and information ROR over OSS components 38. Digital repositories software
Dspace + Fedora = Duraspace 39. Advanced content provisioning and preservation functionalities 40. The core element for an interoperable repositories infrastructure 41. Preparing for operation as SaaS and over IaaS Cloud
42. Future work and informational links
43. Back port features to existing repositories 44. Integrate to OJS the page by page functionality 45. openABEKT 46. Automate already existing economies of scale:offer SaaS capabilitiesfor the whole range of tools Links
