Background
The workflow engine realizes the circulation of an abstract flow, the realization of specific business needs to be completed in an electronic form module, for example, documents are signed and the examination and approval opinions correspond to a business module, the specific business is realized in the business module and the data is stored in a database table, so that the persistence of the business data is realized. The workflow engine is responsible for connecting the service modules in series to realize the circulation of the service flow. The workflow circulation-based electronic form is obviously different from the traditional electronic document which only can exist as carriers of static and fragmented information, pictures, graphs and the like, can be an electronic, common and convenient-to-use almost any type of document, such as electronic documents frequently used in the fields of electronic government such as online declaration, approval, internal office, government information acquisition, submission and the like, and can substantially apply an XML document technology, so that the optimal characteristics of paper documents such as familiar appearance and feeling are reserved, and meanwhile, powerful business logic functions such as data verification and routing instructions are added. These features provide people with the necessary data access and interaction functions while also allowing governments to interact more efficiently with public applications. The workflow list engine system realizes the low coupling connection of the electronic form and various actual business logics, so that the traditional electronic form is really fused with an application system.
The worldwide Standard date of 14/10/2016, the State standardization administration Committee formally approved the release of the independent technology-based national Standard GB/T33190-2016 electronic document storage and interchange Format document (OFD). The OFD, abbreviation of Open Fixed-layout Document is an electronic file format Document format which is independently controllable in China, and the corresponding international standard is PDF. The OFD format file is obtained by fixed layout, no layout run and what you see is, and can be regarded as 'digital paper' in the computer age; is an ideal document format for electronic document publishing, digital information dissemination and archiving. The format data stream file is a file format which can be attached to a bottom plate (pdf, ofd, video and web pages), a single file is supported, a plurality of files or a plurality of types of files are attached at the same time, the original files and the endorsement content can be checked and previewed without modifying and damaging the original attached files, the content vector of the format data stream file is stored and amplified without distortion, the file can be expressed by a character string, can be directly stored in a database and embedded into a workflow system for endorsement and circulation, the file elements comprise pages, blocks, characters, handwriting, voice, pictures, videos, hyperlinks and other common table elements, each element supports related actions, and the page opening trigger or the click element trigger.
