Abstract
The invention relates to a permanent filing system for network academic resources, in particular to a software system for permanent filing of the network academic resources, belonging to the technical field of information storage. In the invention, a set of distributed storage solution based on grid technique is designed on the account of the characteristics of network academic resources, which can effectively support the permanent filing of the network academic resources.
Description
Technical field
The present invention is a kind of network academic resources that is applicable to, based on the permanently filing system of gridding technique.On subject, belong to Modern Library, the category of Information Management.
Background technology
Network academic resources is on the internet and digitalization resource academic pertinence.The network academic resources enormous amount, of a great variety, subject broad covered area, and have certain learning value is traditional academic resources, for example the important supplement of academic journal.
The dynamic person's character in internet has determined network academic resources to have changeableness, tends to occur problems such as link fails, and permanently filing is difficulty quite; At this difficult problem, native system uses the permanently filing system based on gridding technique, realizes the permanent preservation to network academic resources.Its basic thought be with each network academic resources distributed store on a plurality of servers, and for it distributes globally unique identifier, introduce archive server then and keep Globally Unique Identifier to the mapping of the one-to-many between the physical copy address, make application end only need know that Globally Unique Identifier just can obtain a copy, and need not understand the details of storage.
Summary of the invention
The present invention has disclosed a kind of permanently filing system that is used for network academic resources, belongs to Modern Library, the category of Information Management.Native system is at the characteristics of network academic resources, on a plurality of servers, and is each network academic resources distributed store that it distributes globally unique identifier, and keeps the one-to-many mapping of Globally Unique Identifier to the physical copy address with archive server.Like this, application end only need know that Globally Unique Identifier just can obtain a copy, and need not understand the details of storage, thus the permanent storage of network enabled science effectively.
At first, the found network academic resources of each bar all distributes an identifier that the overall situation is unique earlier, is referred to as " GUI " (be Guodao Unified Identifier, wherein Guodao is a registered trademark); In a single day GUI is assigned with, and just can not change, to guarantee that network academic resources in use can be by correct being associated with a resource of GUI again.
The second, the found network academic resources of each bar all has one or more network linkings address, when same network academic resources reprinted by a plurality of websites, behind the mirror image, this resource has all been pointed in each address, in other words, each address correspondence a copy.To each network academic resources, set up the one-to-many mapping of GUI like this to the copy address list.
The 3rd, the found network academic resources of each bar all downloads to this locality, and is distributed on the mirror image server of a plurality of centers, for example is distributed on online mirror image server in center and the center off-line mirror image server.Then upgrading mapping table, just is each GUI, and the copy address of each center mirror image server is increased in its object listing.Then archive server is deployed on the mirror image server of center, and the document server uses the mapping table after upgrading.
The 4th, except copying to the center mirror image server, also be dealt on the local mirror image server, upgrade mapping table then, just to each GUI, the address of local mirror-image copies is increased in its object listing.Next, at local mirror image server deploy archive server, and the document server uses the mapping table after upgrading.
The 5th, when archive server is resolved globally unique identifier, follow following strategy: local mirror image, centre mirror picture, original the Internet source.
The 6th, the validity of archive server cyclic check copy address is to remove invalid copy address.
The advantage of this programme
At the characteristics of network academic resources, this programme has used multiple backup mode, has effectively guaranteed the permanent of data storage and the convenience that uses.
The first, network academic resources can forever exist.Each network academic resources all has one or more copy addresses on network, as long as an effectively copy address is arranged, network academic resources is just available.This programme has also used centre mirror picture and local mirror-image copies except address, the original source of internet usage, each network academic resources has three mirror back-ups so at least, is enough to guarantee the permanent of network academic resources.
The second, every network academic resources all is assigned with a Globally Unique Identifier GUI, GUI is comprising information such as network academic resources name, management, archive server is kept GUI and is arrived the one-to-many mapping table of copy address to resolve GUI, make application end only just can obtain a copy, and need not be concerned about concrete physical store details according to GUI.
Specific embodiments
1, configuration documentation server, archive server are responsible for distributing, manage, are resolved GUI, need installation database system and gui software system on the archive server.Archive server need be configured on center mirror image server or the local mirror image server, and archive server has many to back up mutually, so that uninterrupted service to be provided.
2, data acquisition.Network academic resources is by the professional editor manual mode, from network collection to the center mirror image server, in gathering, each bar resource all will be distributed GUI by archive server, each bar resource is all stored according to dependency rule, after storage is finished, upgrade archive server, make the network academic resources on GUI and the center mirror image server carry out relationship maps.
3, in the data acquisition, for the corresponding a plurality of network addresss of same resource, each address is all joined in the archive server GUI in the mapping table of physical address.
4, the backup of center mirror image server, network academic resources need be done offline backup after downloading, and same, these backup address also will be added GUI in the one-to-many mapping table of physical address.
5, network academic resources is distributed on the local mirror image server, and every resource all has one to multiple local mirror image, and upgrades GUI accordingly to the one-to-many mapping table between physical address.
6, periodic maintenance archive server, the physical address of the network academic resources that check to lose efficacy, and invalid address removed from mapping table.
7, the parsing of GUI, archive server should provide the analysis service of the GUI of 7x24, and a plurality of resource address links that obtain after the parsing offer the user according to different priority levels.Order with original source, mirror image server internet, local mirror image server center provides the fastest access mode to application end.
