1. Service orientation
Digital Archives establishment mainly serves informationizing electronically various information assets preserved in oil companies. After revising, verifying, editing, description, etc., we make them accord with certain standards and also normative, searchable, publishable, available. The information source includes two types: physical data and electronic data.
2. Service goal
The service goal of Establishment for Digital Archives is standard editing archives sources, and then uniformly fitting them into system platform for management and application.

3. Service items
3.1 Standard editing archives
The standard editing informationize electronically various information preserved in archives, after revising, verifying, editing, description, etc., the information will be standard, normative, searchable, publishable, available information sources.

3.2 Metadata plan
The Metadata plan is adopting methods of description, etc. With more information to descript file documents, so user can accurately understand files without knowing files’ details; the plan can also provide convenience for huge amounts of files cataloguing and expert searching.
Jurassic company offer Metadata plan according to oil industry requirements of files application. After metadata excerpt and summary, user can manage spatial data and solve the problem of multiple linear management and rapid query by making use of computer technology.

3.3 Files application platform plan
Files application system is to form a technological achievements resource database with function of uniform storage, organization and management, make information service for researchers.
1) Files management
o Forming files center cataloging function
The below picture shows the digital files center cataloging plan during implementing of a project finished by Jurassic company. The plan forms digital files cataloging based on five clues, which are Professional files, Structure units, Oilfields, National geological data classification, and data generating units.

4) Security regime
Offline electronic files security control is one of the most important links in the management system, by limiting reading times and reading period of PDF files downloaded by clients, preventing random distribution of PDF files, preventing saving copies by clients, and automatically destroying the expired files, security regime can insure the files’ safety.
4. Service features
4.1 Integrity and comprehensiveness
Establishment of Digital Archives plan service includes editing data sources, establishing software platform, consulting and establishing work procedure, establishing of supporting system. The service satisfies all aspects of requirements from a mature service, so the advantages of integrity and comprehensiveness are unique.
4.2 Standardization and specialization
Jurassic, the company's professional service cannot only satisfy general industry standard, but also deep studies and practices in industry segmentations, it can fully support Petrochina and Sinopec system's latest standards. Archives, cataloging, item description, etc. can be fully customized and preset-up, which ensure the flexibility and standardization; In archives management, for paper files(or other entities),adopting fast segmentation description for paper files, visual physical memory address management, bar code management, borrowing sheet etc.; for electronic files, adopting files offline control, watermark management, which satisfy the professional requirements.
4.3 High degree of safety
Jurassic geological archives management system has a high degree of safety. Firstly, adopting high degree of safety design for developing tools and establishment of frameworks; secondly, optimizing the design of permissions model, so it can achieve control ability level up to “files/ archive” to "role/user"；meanwhile，Jurassic company developed many specific techniques for files security to maximally ensure files safety; In addition, the safety and standard working procedure also ensure that the system will not appear any files security problems during the framing work.
4.4 Long-term and sustainable development
Jurassic geological archives management system is based on the open model of XML information exchange, and designs the framework based on interface component. Those designs ensure that the system has a very strong adaptation ability, service ability and extension ability; therefore, it has the very strong vitality. By extension, upgrades it as a distributed digital archives management system, multiple digital archives system can be connected as a large distributed network digital archives, files processing ability and application will expand further.
