2. Page 2 3. 10. 2008 Thomas Willmann Introduction Data corrections after transmission to Eurostat cause a lot of work and lead to additional errors and uncertainties as to which version is the correct one. The German cities cooperating in the "KOSIS- Gemeinschaft Urban Audit" decided therefore to technically support the next round of data collection by programmes that check the data as they arrive from the different sources."

3. Page 3 3. 10. 2008 Thomas Willmann Structure There are 6 data packages in the German data collection (according to the different data sources): 40 cities with 85 variables 40 cities for the subcity data (700 units) with 110 variables 40 cities and 32 LUZ from RegioStat with 190 variables 40 cities and 32 LUZ from Microzensus with 50 variables 40 cities and 32 LUZ from Federal Labour Agency with 70 variables 40 cities from different sources with 25 variables

4. Page 4 3. 10. 2008 Thomas Willmann Data collection The city data and the subcity data will be delivered from the cities with decentralized aquisition The other four data packages will be delivered from different institutions with centralized aquisition

5. Page 5 3. 10. 2008 Thomas Willmann Technical concept All data are stored in a central database All data collection from the cities is done via internet to this database An individual template is provided for each data source There is a possibility for uploading data from ascii-files

6. Page 6 3. 10. 2008 Thomas Willmann Individual forms Every user (city) has his own id and password Every user can collect and edit his own data The form shows for every variable the values from the previous found of collection During editing the form, input data can be checked with different rules (totals, difference to value of the previous round of collection)‏ The rules can point to errors (which have to be corrected) and to warnings (which can be ignored)‏

11. Page 11 3. 10. 2008 Thomas Willmann Central database Data checking between files (e.g. subcity and city) will be done in the central database after data collection Data for transmission to EUROSTAT will also be prepared from this database The data can be used online by the cities for individual evaluations

12. Page 12 3. 10. 2008 Thomas Willmann DUVA software The software for the German data collection is part of the DUVA metadatamanagent software The main module is the metadata repository NWS With the form-generater you can create data entry forms with mask specifications (layout, rules)‏ using the metadata Another module is the data entry module for pc or for web-site with the created data entry forms The Internet Assistant allows user defined online tables, charts and maps using the metadata
