Abstract

A method to locate sub-component of file/resource in data sharing system. Method could parse the target file/resource in order to extract or generating sub-component to present part of the target resource in specified context. Method then is able to assign identificator, including but not limit to IRI/URI, to sub-component in target file/resource.

component in data sharing system under variable contexts

In common data sharing system, database(RMDB and Non-SQL), OS file system, binary repository etc, resources like file or jar are located as an entity, and resources are updated in lifecycle as a whole.

However it is inconvenient to maintain the lifecycle for resources within some use cases. For example, a document in data sharing system, when user would like to fetch part of the document, like first 3 chapters, With existing system, there is no way for user to locate the exact chapters they are interest in, users need to firstly fetch the whole document, then refer to the parts of interests. Also, if user would like to update part of the document, like updating the third paragraph, they have to replace the old document with the new one in data sharing system.

In above use cases, unnecessary effort are spent on fetching and updating data which are not needed, that is because there is no way for existing system to split resource for partial update. Also, existing system could not split date resource according to data resource's property and use case context.

A method to locate sub-component of file/resource in data sharing system. Method could parse the target file/resource in order to extract or generating sub-component to present part of the target resource in specified context. Method then is able to assign identificator, including but not limit to IRI/URI, to sub-component in target file/resource.

Method presented has following functionalities:

1. Subcomponents could be created/generated by customized parser to allocate identificator t

2. Subcomponents are able to be comparable(like diff, ETag) based on meta-datagenerated with sub-component;

3. The scope of sub-component offered by method is able to be specified by request according to the context of target data resource;
4. Method is able to store/update existing sub-components, update in sub-component is able to reflected in original data source;

Compared with existing

                data sharing system/method, current method allow request to locate part of the data source, for fetching or updating, extra data flow out of users' interest will not be involved.

Also, scope of subcomponet is able to be specified in method presented, which supports different use case. For exmaple, if user would like to fetch the first 3 chapters of a documentation, method is able to split first three chapter of target resource an...
