This number, and the local version number of the specified metadata is adjusted to the complete of current all offspring's metadata of specified metadata
Maximum value in version number, office copy.
It is described to include: according to the change operation adjustment global version number in an alternative embodiment of the invention
In the case that metadata in each pair of metadata management system executes the primary change operation, to the global version
It number is once updated, wherein change operation is executed to multiple metadata in the metadata management system in the same time
In the case where, only the global version number is once updated.
Optionally, global version number can be long, and be an overall situation within the scope of metadata management system
Property variable.
Optionally, described be updated to the global version number according to the first predetermined way includes: to global version number
Add 1, using the value arrived as updated global version number；The metadata in each pair of metadata management system executes
In the case where the primary change operation, carrying out primary update to the global version number includes: to add 1 to global version number, will
The value arrived is as updated global version number.
In the above embodiment of the invention, specified metadata can be any one first number in metadata management system
According to, and be any one metadata definition one global version number's copy and part version in metadata management system
Number, i.e., each metadata in metadata management system includes global version number's copy and local version number.Offspring
Metadata can be with the specified metadata there are the derivative metadata of incidence relation, for example, offspring's metadata can be pair
Metadata executes the new metadata generated after newly-increased operation.
It is illustrated below in conjunction with method for edition management row of the example to above-mentioned metadata, but is not used in and limits this hair
The technical solution of bright embodiment, the exemplary technical solution of the present invention are as follows:
Step 1, global version number (Global Version Number, GVN) is defined.In embodiments of the present invention, GVN
It can be long type, and the variable of overall importance in a system scope.Optionally, above system can be metadata pipe
Reason system, i.e. GVN can be a variable of overall importance in metadata management system.
Step 2, a GVN pair is defined for each of metadata management system metadata object (also known as metadata)
This.When changing metadata object, the GVN copy of the metadata object is updated according to the type of change operation.
Step 3, offspring's maximum version number (Descendant is defined for each of system metadata object
Version Number, DVN, i.e., the local version number in above-described embodiment).DVN is a locality variable, each first number
According to oneself DVN has all been separately maintained, it is referred in all offspring's metadata of the metadata object, the maximum of GVN copy
Value.For example, there are two offspring's metadata B, C for metadata A tool, and the GVN copy of offspring's metadata B, C is 3,4 respectively, then first
The DVN of data A is the maximum value of the GVN copy of offspring's metadata B, C, and the DVN of metadata is 4.
Step 4, GVN, metadata are adjusted (when executing change operation to metadata) when metadata object changes
The GVN copy of object and the value of DVN.
In embodiments of the present invention, can to metadata object execute change operation, the change operation can be with down toward
It is one of few: newly-increased (insert), to delete (delete), update (update).After performing change operation to metadata object,
The metadata changed is identified using metadata evolution label.In embodiments of the present invention, metadata tag includes:
It disappears (faded) and has changed (altered), wherein disappearing indicates that corresponding metadata has been deleted, and has changed expression and corresponds to
Metadata be updated.Table 1 may refer to the detailed description of change operation, table 1 is metadata according to an embodiment of the present invention
Change operation accords with table, wherein each operator corresponds to a kind of change operation.The detailed description of metadata table more label can be joined
2 are shown in Table, table 2 is metadata evolution label list according to an embodiment of the present invention.
Table 1
| Names of operators | Explanation |
| insert | Increase metadata newly under metadata |
| delete | Delete metadata |
| update | Update metadata information |
Table 2
| Metadata tag title | Explanation |
| faded | Identify deleted metadata |
| altered | The information of metadata has changed |
In the above embodiment of the invention, the metadata in record metadata management system is recorded using graph data structure
And when offspring's metadata, it can also be indicated in the graph data structure using operator and change performed by metadata is grasped
Make, and indicates the metadata changed and offspring's metadata respectively using metadata tag.
In the above embodiment of the invention, when executing newly-increased operation to metadata object, after GVN adds 1 to obtain update
GVN, and be updated using GVN copy of the updated GVN to the above-mentioned metadata object changed, i.e., by this yuan of number
According to GVN copy be set as the value of current GVN.
In one embodiment of the invention, if a certain batch metadata changes simultaneously, the value of GVN only be will increase
Once, that is to say, that the metadata after these changes is owned by identical GVN copy.
Optionally, whether offspring's metadata that the DVN of metadata can be used for quickly detecting the metadata is changed.
When offspring's metadata is not present in a certain metadata object, the DVN of the metadata object is default value, if it exists offspring's member number
According to then using the maximum value of GVN copy in all offspring's metadata of the metadata object as the DVN of the metadata object.
In one embodiment of the invention, all members changed can be traced by above-mentioned three kinds of action identifiers
Data, and metadata tag can be used, when user carries out full library inquiry, shield the metadata for disappearing or having changed.Fig. 2
It is the schematic diagram of the method for edition management of metadata according to an embodiment of the present invention, as shown in Fig. 2, indicating in graph data structure
Out to the change operations such as newly-increased performed by metadata, deletion, the GVN copy and DVN of metadata, and use metadata tag
The metadata changed is indicated, for example, " disappearance " is used to indicate the metadata being deleted, " variation " is used to mark
The metadata that change (having updated) occurs for information is shown.
By the GVN copy and DVN of each metadata, the efficient management to metadata version may be implemented.In this hair
In bright one embodiment, the GVN copy that can be held according to each metadata, only need to carry out a condition query (for example,
Input the range of GVN copy), so that it may the metadata for getting those generation changes between any old version passes through GVN
Copy and DVN can recorde the change history (for example, newly-increased metadata, deletion metadata, more new metadata) of metadata, thus
The change history of source can be traced, it is synchronous with the data of source convenient for subsequent acquisition end, it is ensured that the number of collection terminal and source
According to consistency.
Through the above description of the embodiments, those skilled in the art can be understood that according to above-mentioned implementation
The method of example can be realized by means of software and necessary general hardware platform, naturally it is also possible to by hardware, but it is very much
In the case of the former be more preferably embodiment.Based on this understanding, technical solution of the present invention is substantially in other words to existing
The part that technology contributes can be embodied in the form of software products, which is stored in a storage
In medium (such as ROM/RAM, magnetic disk, CD), including some instructions are used so that a terminal device (can be mobile phone, calculate
Machine, server or network equipment etc.) execute method described in each embodiment of the present invention.
