In 2007, an issue of state-wide legalization of specification of an electronic document signed by an electronic signature was raised at the interinstitutional level. Several public institutions including the Department of Archives of Lithuania were appointed to prepare the requirements for the specification.
The specification of an electronic document is a document describing the technical properties, characteristics, and functions of an electronic document signed by an electronic signature and establishing the requirements for ensuring the interoperability of different software tools and other requirements. It defines the three requisite parts of an electronic document: structure of the content, metadata, and electronic signatures stored in the package of an electronic document.
Having analysed the regulatory environment and international experience in the field of management and storage of electronic documents and electronic signature technologies, the Department of Archives of Lithuania in 2008 prepared the description of the requirements for the specification of an electronic document signed by an electronic signature, which created the preconditions for legalization of the specification of electronic documents signed by electronic signature. The Description of the requirements for the specification of an electronic document signed by an electronic signature currently in effect lays down the minimum requirements for electronic documents of equivalent to written documents only.
In 2009, the Specification of Electronic Documents Signed by Electronic Signature ADOC-V1.0 equivalent to written documents was approved. It is currently most widely use in public institutions of Lithuania. In order to ensure the compatibility of electronic documents, the specification was prepared based on open format and electronic signature standards and recommendations.
An electronic document compliant with the ADOC specification is comprised of the content, signed and non-signed metadata, and electronic signatures (electronic signatures compliant with the standard XadES) stored in a ZIP package.
After the Description of the requirements for the specification of an electronic document signed by an electronic signature came into effect, other specifications of the electronic documents signed by an electronic signature were prepared and are now used in special activities of public institutions. Those are the Specification of a Document Signed by Electronic Signature in the Electronic Service System for Residents (EGAS V1.0) used in the activities of State Social Insurance Fund Board and Specification of an Electronic Document Signed by Electronic Signature and Read by a Computer (MDOC-V1.0) used in the activities of State Tax Inspectorate under the Ministry of Finance. According to these Specifications, electronic documents must also be signed by electronic signatures compliant with the standard XadES.
It is noteworthy that in 2011, in the conference “e.Demokratija: įvesti” (“E-Democracy: Introduce”) organised by the movement “Aš Lietuvai”, the awards of “Lithuanian E-Achievement” were presented. The service was nominated for “E-Achievement: National Strategic Innovation” for the unified format of electronic documents ADOC/MDOC.
The compatibility of electronic documents created according to the specifications allows transferring an electronic document created in one system to any other system and verifying the authenticity and suitability of an electronic document for long-term storage, if it is included in the functions of the systems.
