Beginning October 1st, 2010, all government institutions are obliged to upload their acts and decisions on the Internet with special attention to issues of national security and sensitive personal data. Each document is digitally signed and assigned a unique Internet Uploading Number (IUN) certifying that the decision has been uploaded at the “Transparency Portal”. Following Law 4210/2013 of the Ministry of Administrative Reform and e-Governance, administrative acts and decisions are not valid unless published online. The public consultation procedure is open to everybody. No minimum time periods are foreseen for consultation. It is not clear whether the comments obtained from the public are taken into account. Law 4727/2020 regulates the obligation for digital transparency as well as the Programme of “Diavgeia”. Greece has also launched Geoadata.gov.gr for providing open geospatial data and services (link: http://geodata.gov.gr/content/about-en/ ).See: http://diavgeia.gov.gr/en regarding the purpose of the programme and:http://www.opengov.gr/en/ to gain access.Unofficial link to Law 4727/2020: https://www.taxheaven.gr/law/4727/2020
