MODEL OF ELECTRONIC DOCUMENT
![Page 8: Electronic Archive Information System](https://reader037.vdocuments.mx/reader037/viewer/2022102910/56814326550346895daf926d/html5/thumbnails/8.jpg)
Interoperability problem
• The main standardizations efforts in the EU are still targeted to electronic signature formats.
• Member states should be able to process (validate) the e-signatures formats: XAdES, CAdES, and PAdES.
• The true artifact of interoperability is an electronic document.
![Page 9: Electronic Archive Information System](https://reader037.vdocuments.mx/reader037/viewer/2022102910/56814326550346895daf926d/html5/thumbnails/9.jpg)
Conventional official documents
Very complex entity:• Various content• Appendices and/or attached independent
earlier created documents• Signed by one or more signatures• Registered and possesses corresponding
attributes
![Page 10: Electronic Archive Information System](https://reader037.vdocuments.mx/reader037/viewer/2022102910/56814326550346895daf926d/html5/thumbnails/10.jpg)
Official electronic documents
• Should be adequate to the conventional documents
• Consist of three parts:- content, - signatures,- metadata.

Product line Signa
• Signa Desktop – public free Windows OS application (download from http://www.mitsoft.lt/)
• Signa Web – public free web application (available at https://signa.mitsoft.lt/)
• Signa SDK – a set of application libraries for Java and .NET platforms (supports all current specifications)
• Signa Docs – web application for enterprises (featuring multiple users, electronic document workflows and the ability to sign with qualified signatures multiple electronic documents in bulk; ELPAS is based on it)

Project goal
To create an integral open IS for accepting and storing electronic documents of National Document Fund (NDF), providing a legal access to the stored documents using IT and communication means, administering NDF efficiently and providing electronic services.
![Page 16: Electronic Archive Information System](https://reader037.vdocuments.mx/reader037/viewer/2022102910/56814326550346895daf926d/html5/thumbnails/16.jpg)
EAIS important features
• Deals with electronic documents that are original documents, having the same legal value as handwritten (handsigned) documents.
• Assures the integrity, authenticity, non-repudiation and possibility to use the electronic documents for a long or unlimited time.
The system is unique (we do not know other corresponding system).

EAIS main parts
• Public portal• Internal portal• Storage of electronic documents:
- physically located in Vilnius and Šiauliai- data replication- accessible through internal portal only
![Page 18: Electronic Archive Information System](https://reader037.vdocuments.mx/reader037/viewer/2022102910/56814326550346895daf926d/html5/thumbnails/18.jpg)

EAIS important functionality
• Authentication of external users through e-government gateway
• All public functions could be invoked interactively and through corresponding Web services
• Flexible configuration of authenticity checks• Retention risk management:
- converting content into long-term storage files (PDF/A format)- extending e-signatures to XAdES-A format- means for physical preservation of electronic documents

EAIS conclusions
• EAIS has been launched in October 2011. • The first national archive storing electronic
documents signed with qualified e signatures.• Currently EAIS deals with electronic
documents of ADOC and EGAS specifications.

Actions in progress
• PDF-LT specification.• Adjustment of the Law on Documents and
Archives.• Transfer of Government decrees (electronic)
to EAIS.

Summary
• “Standard-first” approach should be chosen.• ADOC and MDOC specifications were
nominated as main strategic innovation 2010 in Lithuania.
• Product line Signa was awarded as a winner of national contest “Innovative Product 2011”.
• Electronic Archive Information System is unique not only in Lithuania, but also in the world.

Advantages of el. documents
• Save time and costs of ordinary post services and/or further management.– The scanning costs per year in Lithuania would
exceed 10 M€.– Average 3-year ROI of electronic documents
management exceeds 300%.• Full reliability of document content,
possibility to use fragments for preparation of other documents, possibility to search in a document text.
