The present invention relates to a metadata template based learning content metadata authoring system and authoring method, and more specifically, to interoperability and cooperative learning in a multiplatform environment (PC-to-Mobile-to-DTV). The present invention relates to a metadata-based learning content metadata authoring system and an authoring method for managing the creation, modification, deletion, and storage of learning content metadata.

Learning content metadata is provided to learners, instructors, and others who want learning content metadata information through Internet-based e-learning. The users (learners, instructors, and others) can collect and select desired learning information, and can edit and process them.

Here, e-learning replaces existing limited learning in time / place / content with learning of immediate / daily / customized / adaptive progression. It is based on the conceptual category of management / culture / IT.

The metadata is data about data (data data) (information data about data data), and means data having various information about the data, not actual content. It is also a structured data that is independent of resources and is a record containing various access points and location addresses. Metadata includes the basics such as attributes, structure, and connectivity of data, and provides high utilization of information by playing a crucial role in storage, retrieval, management, operation, and maintenance in application system. . In general, there are three basic pillars of metadata: data management, data access, and data analysis. These functions can be used to enhance interoperability and sharing among resource discovery tools.

In addition, the authoring system, that is, authoring tool (Authoring Tool) is a professional program for making a general application even without programming expertise, and a development program that can create various programs such as programs using a standardized method and a user interface easily. Say The authoring tool makes it easy to implement the program creation screen because most title productions display or move different screens according to the response of the mouse or keyboard to text or pictures on the screen, and freely move the desired screen. As it enables, it is widely used in multimedia title production. Here, the production of multimedia titles refers to the production of software having a storyline by connecting multimedia data such as images, images, and voices by hyperlinks according to a specific intention in the computer software field.

Recently, with the rapid increase of Internet users and the development of high-speed communication technology, anyone can easily obtain the desired information by accessing the Internet through the network. At the same time, the educational environment is also changing with the spread of personal computers and the development of information and communication technologies.

Hereinafter, a learning content metadata authoring system and an authoring method based on the metadata template of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a learning content metadata authoring system according to the present invention.

As shown in FIG. 1, the learning content metadata authoring system is largely comprised of a user terminal 100, an interface 200, and a learning content metadata authoring server 300.

The learning content metadata authoring server 300 may generate, modify, and delete a metadata schema and provide an edit screen of the learning content metadata, and the learning content metadata changed by the input unit 310. Create and manage a metadata database 330 for storing changes, a storage structure for storing generated or modified learning content metadata, and exchange / process data for importing or exporting stored learning content metadata to the outside. It includes a controller 320.

The controller 320 manages XML and management information according to a metadata schema defined by a schema designer of learning content metadata, and satisfies all functions of a known metadata manager.

In addition, the input unit 310 performs a function of inputting and editing learning content metadata. In addition to the function of creating, modifying, and deleting a schema as described above, a function of inputting learning content metadata, a user verification function, and XML Perform the transformation function and learning content metadata verification function.

It is well known that the functions performed by the input unit 310 and the controller 320 are modularized for each function.

FIG. 2 illustrates the internal structure of the input device of FIG. 1 according to the present invention, wherein the input device 310 includes a learning content metadata schema editor 310a and a learning content metadata record for creating, modifying, and deleting a schema. And a learning content metadata record input unit 310b that provides an editing screen.

Using the learning content metadata authoring server 300 according to the present invention as described above, the user terminal 100 is contacted through the interface 200 to create, modify and delete the desired learning content metadata to manage or desired learning. You can retrieve content metadata. Here, the user terminal 100 includes not only an author who substantially generates and manages learning content metadata, but also a user who searches for already generated learning content metadata to obtain necessary information.

When authoring (or editing) learning content using the learning content metadata authoring server 300 configured as described above, the user terminal 100 inputs desired learning content metadata on its computer in units of SCO, CA, and Manifest. When stored, another user terminal 100 may view the learning content metadata stored in the metadata database 330 located in a specified server or a specific folder through a web browser through his web browser. In this case, it is most preferable that the learning content metadata to be viewed is converted into an XML form and viewed. In the present invention, the conversion function to the XML form is performed by the input unit 310.

Next, a method for authoring learning content metadata based on the metadata template of the present invention having the above configuration will be described with reference to FIGS. 3 to 6.

3 is a flowchart illustrating an authoring process and a learning content metadata retrieval process of the learning content metadata authoring apparatus according to the present invention.

First, the user terminal 100 accesses the learning content metadata authoring server 300 on the web through the interface 200, and then inputs a user ID and a password (S10). At this time, the learning content metadata authoring server 300 checks whether the user terminal 100 has a right to use the system 300 (S20), and the learning content metadata system 300 is granted a use right. If so, authenticate the user. However, if it is confirmed that the system permission is not granted, the learning content metadata authoring server 300 blocks the system permission.

When the user authentication of the learning content metadata authoring server 300 is confirmed, the user terminal 100 generates new learning content metadata, modifies (updates), deletes, or deletes the existing learning content metadata. It is determined whether to retrieve data (S30).

When searching for the desired learning content metadata is selected, the user terminal 100 contacts the desired metadata database 330 to obtain the desired learning content metadata, converts it into XML, and then views it through the XML preview ( S40 to S60).

However, if the learning content metadata input / modification / deletion is selected instead of searching for the desired learning content metadata, the user terminal 100 selects and performs a desired operation during input / modification / deletion (S31). When the above operation occurs, the learning content metadata authoring server 300 automatically checks whether there is an error with respect to the changed learning content metadata, that is, checking the validity (S32). The validity check is performed in real time, and the user terminal 100 can immediately check whether there is an error on the learning content metadata worked by the user terminal 100.

When the validation is complete, the user terminal 100 selects whether or not to preview the learning content metadata worked by the user (S33).

When the preview is selected, the changed learning content metadata is converted into XML and viewed through the preview (S50 to S60).

However, if the preview is not selected, the changed learning content metadata is stored in the metadata database 330 (S34).

4 is a flowchart illustrating a learning content metadata authoring method according to the present invention. The learning content metadata authoring method according to the present invention is an embodiment of the present invention and includes a SCO for processing and managing learning content metadata. The description will be made in units of CA, and Manifest.

First, the user terminal 100 contacts the learning content metadata authoring server 300 according to the present invention through the interface 200 and receives user authentication. Next, the file is opened through the edit screen on the web (S100).

When the file is opened, one of SCO, CA, and Manifest is selected (S200, S220, or S230). 5 illustrates an input screen of the learning content metadata authoring apparatus according to the present invention. 6A shows an input screen of SCO and CA, and FIG. 6B shows an input screen of Manifest.

In FIG. 6A, input screens of SCO and CA may be divided into nine categories: General, Life Cycle, Meta-metadata, Technical, Educational, Rights, Relation, Annotation, and Classification. The detailed description is as follows [Table 1].

division Explanation General Items that correspond to general information that describes the resource as a whole Life cycle Describe the history of the learning content, recent status, and contributors related to the content. Meta-metadata -Item to input specific information about the metadata record itself-Enter information about the person who recorded the metadata, the recording method, and the date of recording Technical Enter technical characteristics of technical requirements and resources Educational Information input to explain the educational aspects of the content Rights Enter information such as intellectual property rights and conditions for all rights Relation An entry that describes the correlation if the learning content is related to other content. Annotation Items that provide information about additional descriptions, i.e. information about the person, date, and content of the additional description. Classification Item that inputs information where resource is located within specific classification

In FIG. 6B, the input screen of the manifest may be a manifest, an organization, a resource, and a sub manifest, divided into four categories. The detailed description is as follows [Table 2].

division Explanation Manifest File representing information for describing content packaging Organization -Input items to provide structure of content-input form for learning content classification structure Resources -Metadata entry to describe external resource-Express whether resources are structured and interconnected Sub manifest -Enter a number of subordinate manifests in the topmost manifest.-Enter the information in lecture units or module units.

As described above, when the entry for each item of the selected SCO and CA or Manifest is completed, validation of the input learning content metadata is performed in real time (S300 to S400).

When the user terminal 100 performing the operation selects the preview of the changed learning content metadata, the changed learning content metadata is changed to XML and previewed through the web browser (S500 to S700).

However, if the preview is not selected, the changed learning content metadata is stored in the metadata database 330 (S500 to S510).

As described above, the present invention divides learning content metadata into SCO, CA, and Manifest to enable authoring, managing, and searching for learning content metadata effective for a user. Thus, users, that is, learners and instructors, can easily create and retrieve desired learning content metadata.

Although the present invention has been described in more detail with reference to some embodiments, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.

As described above, the learning content metadata authoring system and the authoring method based on the metadata template according to the present invention are classified into SCO, CA, and Manifest to generate, modify, or delete the learning content metadata, thereby enabling searching. The user can easily author, manage, and search the learning content metadata, and can also be provided with the desired learning information quickly and accurately.
