1 Data exchange using EDAMIS Item 2.1 of the agenda SISAI-Metadata Working Group meeting 2015

2 Agenda 1. EDAMIS data transfer infrastructure 2. EDAMIS Web Application (EWA) 3. EDAMIS Web Portal (EWP) 4. Intended developments / changes in EDAMIS SISAI-Metadata Working Group meeting

3 EDAMIS data transfer infrastructure The Electronic Data files Administration and Management Information System (EDAMIS) is the integrated environment for data transmissions between Eurostat and the Member States For data delivery two transfer features / protocols are available: EWA / Statel (FTP/HTTP) EWP / EWF (HTTPS) Year Transferred files EWA EWP / EWF (58%) (39%) (53%) (45%) (44%) (44%) (42%) (47%) SISAI-Metadata Working Group meeting

4 EDAMIS data transfer infrastructure Member States Mail smtp Mail Server stopped Data Centre Statel ftp / http Statel Environment Explorer / Robot EWA EWP https EDAMIS SISAI-Metadata Working Group meeting

5 EDAMIS Web Application (EWA) In all National Statistical Institutes, ECB, OECD and some Central Banks the EWA is implemented. Situation 45 installations in the different organisations 42 installations using EWA V3.1.0 or higher. 3 installations using EWA Migration intended in the next few weeks. 4 installations where the user management is not synchronised at the moment. Transfer protocol HTTP used by 22 EWA Transfer protocol FTP used by 23 EWA SISAI-Metadata Working Group meeting

6 EDAMIS Web Application (EWA) Near future The transfer protocol FTP will be stopped because of security constraints. The destination address (URL) for the HTTP protocol will be changed. FTP switch of protocol in all Windows EWA as both protocols are available. Unix / Linux EWA will be changed later. The underlying Statel client has to be replaced. technical person in charge in Member States already asked whether change is possible in their network premises. HTTP change of destination URL New address will be provided when the environment is finally tested SISAI-Metadata Working Group meeting

7 EDAMIS Web Portal (EWP) All EDAMIS users with corresponding rights can send data via the user interface. Three features are available Situation Three features are available at the moment: Send Datafile (simple) - encrypted data delivery via https Send Datafile (advanced) - normal data delivery via https WebForm - special delivery feature via https Near Future A new file upload feature will be operational in July enhanced proxy management in order to avoid network security problems in Member States better performance and possibility to send big data (> 100MB) already tested by several organisations SISAI-Metadata Working Group meeting

8 EDAMIS Web Portal (EWP) SISAI-Metadata Working Group meeting

9 Intended developments / changes in EDAMIS EDMAMIS infrastructure Intended to change underlying EDAMIS infrastructure for several central components: Replacement of operation system platform SunSolaris by Linux / RedHat Migration of web application server Coldfusion from V8 to V10 Change should be realised transparent for end users, i.e. there will be no long interruption of the service EDAMIS Web Forms (EWF) Modification of the code used for this transfer feature. Increasing number of problems with Java Feature has now reached its limitation Analysing of the future of EWF component has already started SISAI-Metadata Working Group meeting

10 Intended developments / changes in EDAMIS WebService The current transport layer was developed around years ago. There are restrictions on the current transmission protocols of Statel Requests by several Member States to have the possibility for a direct application to application communication via WebService Analysing of the new feature has already started SISAI-Metadata Working Group meeting
