It was launched in June 2008.
It is geography for GIS (aka Geographic Information System).
Yes! Just choose the dataset(s) you are interested in on the confirm import page. If you want to import an other dataset later, a workaround is possible
It depends on the machine and the memory. On a core2 Duo it takes about 40 hours . The importer is useful if you are interested on an custom import(specific placetypes, countries, dataset...), If you don't want to run an import by yourself, because you are interested in all placetypes for all countries, a Postgres dump and a Solr dump can be found here. it will takes only the time to inject the dump into Postgres and copy the Solr dump into the solr directory (~1 hours)
The import is long because :
It has been tested on several machines using linux, Windows and various JVMs. Gisgraphy has a high unit/integration test coverage. it is scalable, and heve no memory leak (
Yes, I plan to keep the development going.

Java / Spring / Hibernate / Hibernate Spatial / Maven 2 / PostGIS / PostgreSQL / struts2 / SolR-Lucene.
No (and it will never be). Oracle is commercial and it does not follow opensource philosophy, and MySQL needs MyISAM database. You can not do GIS with MySQL and InnoDB. There is a real limitation because foreign keys are missing in MyISAM.
Gisgraphy is designed and have been tested for Java 1.5 and later .
Not yet, but probably in v 4.0 (no date)
Edit the importer.filesToDownload option in the env.properties file. Set the country you want to download, then start gisgraphy, go to the admin menu=>run import . Or, if you don't want Gisgraphy to download files; set the importer.retrieveFiles option to false and put the files you want to process in the 'importer.geonames.dir' directory.
Because the data are pre-processed : we extract streets, calculate the length, the middle point, clean some values, improve names (especially for fleet tracking), and so on. an other reason : we thought that it is simple to import csv, instead of a complicated XML one ;)
Yes, you can find some information here.
