Greece / 2013 40% open

Expenses are published as part of the “Clarity” program of Law 3861/2010, which introduced for the first time in Greece the obligation to publish all the decisions of government and all administrative entities on the Internet.

According to Law 3861/2010, article 7 /τ.Α΄112 -13.7.2010 all laws, Ministerial Decrees, Presidential Decrees and other regulation of Greece become available online for free through the website of the National Printing Office.

The General Accounting Office is responsible for the dissemination and publicity of the Annual Budget. Unfortunately, the General Accounting office has chosen to publish the related data in formats, which essentially prevents further use of this information by the public. The annual budget is published as unstructured PDF documents, while the internal breakdown formations change almost every year. This makes comparisons of actual spending with the budget , particularly difficult. Some experimental projects have been made using data scraping techniques , however, for a reliable and efficient solution the General Accounting Office should re-evaluate the data publishing policies applied.

It is uncertain if the register exists, but there is an available API at http://www.gsis.gr/gsis/info/gsis_site/PublicIssue/wnsp/wnsp_pages/wnsp.html

You can search for a postal code : http://www.elta.gr/en-us/findapostcode.aspx But that does not give you the corresponding geospatial location of that postal code. Unsure if that data exists.
