TL;DR: In this article, the authors present a framework that lets a component developer provide a component user with different kinds of information, depending on the specific context and needs, in the form of metadata, which describe static and dynamic aspects of the component, can be accessed by the user and can be used for different tasks throughout the software engineering lifecycle.
Abstract: This paper presents a framework that lets a component developer provide a component user with different kinds of information, depending on the specific context and needs. The framework is based on presenting this information in the form of metadata. Metadata describe static and dynamic aspects of the component, can be accessed by the user, and can be used for different tasks throughout the software engineering lifecycle. The framework is defined in a general way, so that the metadata can be easily extended if new types of data have to be provided. In our approach, we define a unique format and a unique tag for each kind of metadata provided. The tag lets the user of the component both treat the information provided as metadata in the correct way and query for a specific piece of information. We motivate the untapped potential of component metadata by showing the need for metadata in the context of testing and analysis of distributed component-based systems, and introduce our framework with the help of an example. We sketch a possible scenario consisting of an application developer who wants to perform two different software engineering tasks on her application: generating self-checking code and program slicing.

TL;DR: In this paper, the authors address the problem of how to cope with such intrinsic limits of Web metadata, and propose a method that is able to partially solve the above two problems, and showing concrete evidence of its effectiveness.
Abstract: The World Wide Web currently has a huge amount of data, with practically no classification information, and this makes it extremely difficult to handle effectively. It has been realized recently that the only feasible way to radically improve the situation is to add to Web objects a metadata classification, to help search engines and Web-based digital libraries to properly classify and structure the information present in the WWW. However, having a few standard metadata sets is insufficient in order to have a fully classified World Wide Web. The first major problem is that it will take some time before a reasonable number of people start using metadata to provide a better Web classification. The second major problem is that no one can guarantee that a majority of the Web objects will be ever properly classified via metadata. In this paper, we address the problem of how to cope with such intrinsic limits of Web metadata, proposing a method that is able to partially solve the above two problems, and showing concrete evidence of its effectiveness. In addition, we examine the important problem of what is the required “critical mass” in the World Wide Web for metadata in order for it to be really useful.

TL;DR: The MODAL (Metadata Objectives and principles, Domains, and Architectural Layout) framework is introduced as an approach for studying metadata schemes, including different types of metadata schemes.
Abstract: SUMMARY Although the development and implementation of metadata schemes over the last decade has been extensive, research examining the sum of these activities is limited. This limitation is likely due to the massive scope of the topic. A framework is needed to study the full extent of, and functionalities supported by, metadata schemes. Metadata schemes developed for information resources are analyzed. To begin, the author presents a review of the definition of metadata, metadata functions, and several metadata typologies. Next, a conceptualization for metadata schemes is presented. The emphasis is on semantic container-like metadata schemes (data structures). The last part of this paper introduces the MODAL (Metadata Objectives and principles, Domains, and Architectural Layout) framework as an approach for studying metadata schemes. The paper concludes with a brief discussion on the value of frameworks for examining metadata schemes, including different types of metadata schemes.

TL;DR: In this article, a method, system, and metadata model that allows for the organization of electronic assets, such as songs, videos, documents, images, etc., is provided. But the metadata model also facilitates searching for assets from the virtual libraries and the implementation of permissioning schemes.
Abstract: A method, system, and metadata model is provided that allows for the organization of electronic assets, such as songs, videos, documents, images, etc. Virtual libraries are created based on virtual copies of assets created based on metadata, thereby avoiding copying of the actual assets. The metadata model also facilitates searching for assets from the virtual libraries and the implementation of permissioning schemes.

TL;DR: In this paper, a distributed file system commands the nodes to search for metadata data structures having location information corresponding to a failed device on the network, which can then be used to reconstruct lost data that was stored on the failed device.
Abstract: Systems and methods are provided for scanning files and directories in a distributed file system on a network of nodes. The nodes include metadata with attribute information corresponding to files and directories distributed on the nodes. In one embodiment, the files and directories are scanned by commanding the nodes to search their respective metadata for a selected attribute. At least two of the nodes are capable of searching their respective metadata in parallel. In one embodiment, the distributed file system commands the nodes to search for metadata data structures having location information corresponding to a failed device on the network. The metadata data structures identified in the search may then be used to reconstruct lost data that was stored on the failed device.
