Customer Application Requirements
The electronic archive for tax assessment and collection at the cantonal tax administration authority of Thurgau was introduced in pursuit of a paperless electronic file management system. Comprehensive file management of documents from different sources (such as the collection application, scanned tax declarations, electronically submitted tax declarations) is intended to boost efficiency and enable a standardized archiving process. To this end, the specialized applications abx-tax.gov and abx-tax.pub were connected to the archive via the ECM integration platform ECM.ip. ECM.ip receives documents from various sources and prepares them in accordance with archiving conventions. The process includes transforming and supplementing incoming metadata, converting incoming documents to PDF/A-2 and splitting these documents into individual pages. Incoming documents are batch processed to decouple the specialized applications as far as possible from the archive and its availability.
A 3-Heights PDF to PDF/A Converter is used to convert PDF documents into the PDF/A-2 format for long-term preservation, metadata embedding and validation. PDF Merge Split components were integrated in the ECM.ip landscape of Abraxas IT via JAVA API for the purpose of splitting PDFs into individual pages that are compliant with the standard.
Instead of following the previous paper-based process, around 155,000 tax declarations submitted each year to the 80 offices maintained by the cantonal tax authority are gathered together and submitted to the Scan Center at DuMo Informatik. The files are scanned and the images and data subjected to further processing at the center. The raw data (machine-processed images without human manipulation) are then converted into the PDF/A-2 format and made available for long-term preservation after the application of a digital signature. So-called reference data from the tax declarations is generated to supplement the raw data intended for electronic processing. This data is optimized for DMS (OS|ECM) processing and is also converted to PDF/A-2 format. The PDF/A Validator then verifies that all of the documents flowing into the DMS are fully compliant to guarantee aspects of quality and legal certainty. Documents created using EVA, the specialized application for electronic assessment, are also converted by the PDF/A Converter for the DMS at the cantonal tax administration authority after they have been printed out pending dispatch to the customer.
