Description

System and Method of Multilingual Rights Data Dictionary

The present invention relates to a system implementing a multilingual rights data dictionary (RDD) and a method of referencing the dictionary.

The RDD of MPEG-21 is a foundational glossary for expressing all forms of rights or permissions that support the commerce of digital content, based on the Interoperability of Data in E-Commerce Systems (INDECS) framework. Clear understanding is important because RDD is intended to enable the accurate management and exchange of rights related to digital content.

In the MPEG-21 framework environment, the rights specified by the rights holders of digital items must be understood and enforceable by all MPEG tools. RDD and Rights Expression Language (REL) serve as standards to meet these requirements.

REL is a machine-readable language that expresses rights and permissions using the terms defined in RDD. The REL expresses the use, rights, and rules of use of digital items in XML. Used as a presentation tool.

RDD is a semantic basis for all expressions of rights and permissions defined in the REL. RDD consists of terms with clarity, consistency, integrity and uniqueness to support MPEG-21 REL for the processing of rights and permissions information. It becomes a semantic layer. In other words, RDD provides a clear and complete definition of the terminology used by REL, and it is intended to address the rights management and use of MPEG-21 digital items (eg rights holders, content producers, distributors, end consumers and their systems). Etc.) It enables accurate information exchange and processing.

The RDD structure of MPEG-21 is defined in the manner of making a dictionary. RDD defines a meaning for a term represented by a specific heading, but is a comprehensive dictionary that can map other headings and definitions defined by other authorities. In addition to defining the terms used in the REL, RDD is designed to automatically or semi-automatically map metadata from terms in one namespace to terms in another namespace with minimal loss of ambiguity and semantic consistency.

1 is a diagram illustrating a standard attribute of an RDD term. As shown, RDD terminology includes Headword, Description, Synonym, Genealogy, TermStatus, Family, ContextDescription, and Relationships. Standard attributes such as Relationship, and each attribute has sub attributes such as Language, Authority, Type, and Comment.

RDD is a logical model based on the context model. The meanings of the basic terms in the context model are shown in Table 1 below.

Basic term meaning Agent Subjects of conduct such as individuals, organizations and systems Context What happens Time The time the action occurs Place The place where the action occurs Resource Objects associated with Context except Agent, Time, Place

FIG. 2 is a diagram for describing a context model of RDD. In RDD, a family is a group of relationships that determine attributes inherited from one term to another according to the context model, and derivatives are generated by dividing into 'Action Family' and 'Context Family'.

'Action Family' consists of setting the relationship between ActType and term, and is derived through application of Context Model. For example, the term type of the context model in 'Action Family' in Make is as follows.

1.Make-> BegetsContextType-> MakingEvent

2.Make-> BegetsAgentType-> Maker

3.Make-> BegetsResourceType-> Output

4.Make-> BegetsResourceType-> MakingTool

5.Make-> BegetsTimeType-> TimeOfMaking

6.Make-> BegetsPlaceType-> PlaceOfMaking

'Context Family' has the same structure as 'Action Family', but unlike 'Action Family', a new term is derived only when it is necessary to support mapping or other RDD dictionary functions.

The Quality Type relationship in the 'Context Family' of the Making Event is as follows.

1.MakingEvent-> BegetsQualityType-> Makeable

2.MakingEvent-> BegetsQualitytype-> Making

3.MakingEvent-> BegetsQualityType-> Made

4.MakingEvent-> BegetsQualitytype-> BeingMade

As such, since RDD is a semantic layer of rights, it is very important that the system in the MPEG-21 framework environment correctly interpret the original contents. However, as mentioned above, RDD is described in English. Due to the fundamental characteristics of natural language, translation of English, the official language of RDD, into other languages may cause problems such as deterioration and reduction of meaning. For example, the semantics may be distorted when an IPMP (Intellectual Property Management & Protection) tool using a language other than English interprets the rights that describe the content use contract using RDD terminology. Moreover, even in the global distribution environment of digital contents, even if the same RDD standard is followed without standardization method for sharing and exchanging information, it is difficult to achieve the interoperability distribution platform of MPEG-21.

The present invention was devised to solve the above-described problems, and by registering a standardized term definition for each language in a multilingual RDD registry in advance, and interpreting rights terms with reference to the multilingual RDD registry in various language-based systems An object of the present invention is to provide a multilingual rights data dictionary system and a reference method thereof that can guarantee practical interoperability between systems.

Other objects and advantages of the invention will be described below and will be appreciated by the practice of the invention. In addition, the objects and advantages of the present invention can be realized by means and combinations indicated in the claims.

The present invention for achieving the above object is a local system accessible to a central system having a multi-language RDD registry, the local RDD registry for storing the RDD of a specific language and input rights terms are parsed and referenced with reference to the local RDD registry And a processing apparatus for interpreting the rights term, wherein the processing apparatus accesses the central system to access the right term interpretation information based on the multi-language RDD registry when the right term interpretation information does not exist in the local RDD registry. Get

In addition, the present invention is a central system that can be selectively connected to a plurality of local systems, receiving a right term from a multilingual RDD registry and a connected local system, and extracts interpretation information of the right term based on the multilingual RDD registry. A processing device for delivering to the local system.

In addition, the present invention provides a method for obtaining rights term interpretation information by accessing a central system having a multilingual RDD registry, comprising: a first step of receiving a right term, a second step of parsing the right term, and storing an RDD of a specific language Extracting the right terminology interpretation information from a local RDD registry; and if the right terminology interpretation information does not exist in the local RDD registry, accessing the central system to access the right terminology interpretation information based on the multilingual RDD registry. Receiving a fourth step.

In addition, the present invention is a central system having a multilingual RDD registry, the first step of connecting to the local system having a local RDD registry, the second step of receiving a right term from the local system and the multilingual RDD registry based on the And a third step of extracting interpretation information of the right term and delivering it to the local system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

3 is a diagram illustrating a multi-language RDD registry reference process of the present invention. Referring to the drawings, the multilingual RDD registry 100 may be implemented in a central system. In addition, the local system networked with the central system may include a local RDD registry 200.

The local system may be an IPMP, a digital item adapter (DIA), a digital item processor (DIP), or the like that interprets rights terms based on the MPEG-21 framework.

The local RDD registry 200 stores the right terms standardized for each language according to the characteristics to which the local system belongs.

The multilingual RDD registry 100 is a collection of local RDDs for each language and maps rights terms between different languages. Thus, the local system can access the central system via the network to use the RDDs of other languages as needed to interpret the terminology.

4A through 4O illustrate XML schema of RDD stored in a local RDD registry according to the present invention. As shown, the XML schema of the rights term reflects the standard attributes of MPEG-21 RDD.

In other words, the standardized rights terms of individual languages are basically headword, description, synonym, generalogy, term status, term status, family, and context description. ContextDescription), Relationship, and the like are described. In addition, each property may have sub-properties such as language, authority, type, comment, and the like.

5 illustrates an RDD described in Korean according to the present invention. As shown, each attribute for the 'Adapt' header is described and stored in the local RDD registry 200.

On the other hand, since the multi-language RDD registry is an RDD collection of individual languages as shown in FIG.

To map rights terms between individual languages, the multilingual RDD registry contains logical links to registered headings.

According to a preferred embodiment of the present invention, the <IsTranslationOf> attribute may be added to each right term heading to logically link RDDs of various languages. For example, in Korean, the heading attribute "Adapt."

By adding <IsTranslationOf> Adapt </ IsTranslationOf>, the Korean standardized right term 'adapt' can be correctly mapped to MPEG-21 RDD 'Adapt'.

In another embodiment, the <RddIdentifier> attribute may be used to assign the same ID (eg, the same number) to a right term having the same meaning so as to accurately map the standardized right term of the individual language.

In addition, a method of mapping and extracting rights terms between different languages using the multilingual RDD registry 100 including RDDs of individual languages may be variously applied.

6 is a flowchart illustrating a process of referring to a multilingual RDD registry according to a preferred embodiment of the present invention. In the following description, the local system includes a local RDD registry for storing the RDD of a specific language and a processing device for controlling the entire local system and interpreting the entered rights terms according to a series of processes described below. In addition, the central system controls the entire central system according to a multi-language RDD registry that stores all the RDDs of the individual languages owned by the local system, and a series of processes described below, and interprets the interpretation information of the rights terms inputted from the local system. And a processing apparatus for extracting.

Referring to the drawings, the local system first receives a right term (for example, an XML document including a right term) from various sources and parses the right term (S10, S12). The local system refers to the local RDD registry to interpret the rights terms (S14).

Since the local RDD registry of the present invention stores interpretation information of standardized rights terms of a specific language, rights terms of other languages do not exist in the local RDD registry.

If the rights term entered in the local system is a rights term of another language that does not exist in the local RDD registry, the local system connects to the central system and inputs the rights term into the central system (S16, S18).

The central system extracts the interpretation information of the right term by referring to the multilingual RDD registry and delivers it to the local system, and the local system interprets the right term using the delivered interpretation information (S20, S22, S24).

At this time, the multilingual RDD registry includes a link that logically connects each local RDD with a set of each local RDD, and extracts interpretation information of the right term based on the link.

Further, in another embodiment of the present invention, the multi-language RDD registry includes only link information for logically connecting each local RDD, and connects to another local system based on the link information to access the right term from another local RDD registry. It is also possible to extract the interpretation information.

In this case, the central system can deliver the interpretation information of the rights term extracted from the other local RDD registry to the local system that requested it.

In this case, on the other hand, the central system is required to access another local RDD registry holding the rights term interpretation information, instead of directly delivering the rights term interpretation information to the local system that requires the rights term interpretation information. Only link information (e.g., location information (URL value)) may be transmitted. The local system receiving the link information can directly access the node having the specific language RDD registry and obtain necessary right term interpretation information based on the link information.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of equivalent claims.

According to the present invention, the multilingual RDD registry can be utilized in various applications such as IPMP, DIP, ER, etc., which use a specific language in various languages, regions, and countries, and in particular, supports development of application software in the REL and ER fields. .

In addition, the multilingual RDD registry can provide a basis for data sharing and exchange by securing reliability of meaning between MPEG-21 systems using different languages.
