Abstract
The invention discloses a metadata proposal suitable for permanently filing and using network academic resources, and belongs to the technical field of information storage and retrieval. Aiming at the characteristics of the network academic resources, the proposal extends the Dublin core metadata set, introduces eight key extension elements, such as a resource type, an organization, a set name, and the like, and can effectively support the disclosure, the storage and the retrieval of the network academic resources.
Description
Technical field
The present invention is a kind of metadata proposal that is applicable to network academic resources permanently filing and use, may be used on announcement, permanently filing and the use of academic resource on the internet.On subject, belong to Modern Library, information science category.
Background technology
Network academic resources is the digitalization resource relevant with science on the internet.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; And the sharing of internet and opening also make everybody to issue academic resources on the internet, thus, cause the confusing of resource organizations on the one hand, make again that on the other hand its quality is very different.Under such background, establish metadata specification targetedly, the internet academic resources is carried out the systematization combing, its meaning is more apparent great.
Metadata is data (data that describes data) or " about the data of data " (dataabout data) of data of description, is used for the feature and the attribute of descriptive data base, also is the instrument of description and organizational information resource.But in library science and information science, metadata is extensively used the description of books, periodical, meeting, rules, information and various resources.In Modern Library, finished the norm-setting of MARC (MachineReadableCatalog: be recorded in catalogue on the computer memory carrier, that use computer Recognition and reading) substantially with code form and ad hoc structure.This cover standard has played crucial effects to the permanently filing of books; But, and be not suitable for network academic resources because it is to formulate at the characteristics of books.The invention of this programme produces in the application aspect the books information in order to solve network academic resources.
Formulating the feasible metadata proposal of a cover, is the infrastructure type engineering of a complexity: not only need be participated in by many-sided expert, and need long application verification to finalize the design.This cover metadata proposal has fully been used for reference Dublin Core Metadata collection standard and has been condensed the experience that the storehouse is built in our long-term network academic resources arrangement.
Summary of the invention
The present invention has disclosed a kind of metadata proposal that is applicable to network academic resources permanently filing and use, belongs to the informationm storage and retrieval technical field.This programme is expanded at the Dublin Core Metadata collection at the characteristics of network academic resources, has introduced 8 critical extension elements such as resource type, mechanism, set name, the announcement of network enabled academic resources, storage and retrieval effectively.

The advantage of this programme
At the characteristics of network academic resources, this programme has been introduced 8 critical extension elements, has effectively guaranteed the permanent of data storage and the convenience of using.
1, resource type element, described the type of network academic resources, these types comprise: 11 major types such as paper class, report type, minutes, subject under discussion proposal, special column commentary, statutory standard, new product information, e-book, teaching material, mechanism's publication, patent.Can allow the user retrieve according to specific resource type, and navigation.
2, mechanism's element is described network academic resources founder unit one belongs to, certain school for example, certain research institute, certain scientific research department of company etc.Mechanism's element except retrieval and navigation inlet are provided, also is one of important evidence of evaluating significance of network academic resources.
3, score value is represented the quantized value that network academic resources is worth with this field, can be used as one of foundation of information retrieval sort result.
4, except " identifier (Identifier) ", " source (Source) " two elements are arranged in the dublin core element, this programme also expands centre mirror as address and local mirror image address, except the primitive network link that resource is provided, also have at least two mirror image website links like this.These 4 elements have all pointed to the visit approach of resource, and this multistage storage scheme has improved the availability of network academic resources.
5, network academic resources has been contained multiple subject polytype, lack unified issue standard and unified administrative mechanism, the title of the resource collection with certain continuation property is described with " name set " this element in this programme, it is a kind of neoteric describing method, with the characteristic of mixed and disorderly resource according to set, organization of unity is got up, and makes resource more convenient and quicker in use.
6, in certain set, each resource all has a specific number, and for example, each this procceedings all has the numbering of procceedings, and the periodical of each volume all has volume issue etc., for the series number element that cooperates " name set " to set up is used for describing this number.
7, land used field element indexed resource is delivered geographic position, the residing position of mechanism or founder, makes things convenient for the user to provide according to retrieving or navigate in the geographic position.
