16 Dec 2002TL;DR: In this article, an intuitive graphical user interface for classifying and searching on a plurality of digital images is disclosed, where multiple simultaneous metadata associations and compound searches may be performed, using disclosed methods.
Abstract: An intuitive graphical user interface ( 100 ) for classifying and searching on a plurality of digital images is disclosed. Multiple simultaneous metadata associations and compound searches may be performed, using disclosed methods. Such operations may be performed using simple user actions, which will be familiar to inexperienced or casual computer users who typically want to perform such operations on digital images without a commitment to learning new software or operating paradigms. Metadata is associated with digital images by selecting iconic or thumbnail representations of the images (e.g., 107 ) and dragging the iconic or thumbnail representations to a destination point to either create a new association for a collection of images or to associate a pre-existing metadata item with the images.

TL;DR: In this paper, the authors present a system that retrieves metadata from a memory within a server, so that the server does not have to access a database in order to retrieve the metadata.
Abstract: One embodiment of the present invention provides a system that retrieves metadata from a memory within a server, so that the server does not have to access a database in order to retrieve the metadata. The system operates by receiving a request from a client, which causes an operation to be performed on data within the database. In response to the request, the system retrieves the metadata through a metadata object, which retrieves the metadata from a random access memory in the server. Note that this metadata specifies how the data is stored within the database. The system then performs the operation on the data within the database by using the metadata to determine how the data is stored within the database. Note that this metadata object can be used to service requests from a plurality of clients. Hence, client sessions can share the same metadata, which can greatly reduce the amount of memory used by client sessions. In one embodiment of the present invention, the metadata object contains static metadata specifying how tables and views are organized within the database. In one embodiment of the present invention, the system accesses the metadata object through a generic object on the server.

11 Dec 2006TL;DR: In a distributed electronic messaging system, authorized information comprising metadata concerning a message is passed along from one mail server to another mail server as discussed by the authors, and if the sending computer is not authorized to pass along metadata, the metadata is stripped off the message, changed or annotated.
Abstract: In a distributed electronic messaging system authorized information comprising metadata concerning a message is passed along from one mail server to another mail server. A receiving computer determines if the sending computer has the necessary authorizations to pass along the metadata. If so, the authorized information is passed along with the message body, enabling repetitious actions to be eliminated. If the sending computer is not authorized to pass along the metadata, the metadata is stripped off the message, changed or annotated.

TL;DR: The OAI2LOD Server handles shortcomings of the OAI-PMH protocol by republishing metadata originating from an OAI -PMH endpoint according to the principles of Linked Data.
Abstract: Many institutions grant access to their metadata repositories via the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). However, this protocol has two signicant drawbacks: it does not make its resources accessible via dereferencable URIs, and it provides only restricted means of selective access to metadata. The OAI2LOD Server handles these shortcomings by republishing metadata originating from an OAI-PMH endpoint according to the principles of Linked Data. As the ongoing OAI-ORE specication process shows, these principles are gaining growing importance also in the digital libraries domain.

TL;DR: This work categorizes the major metadata types and their interdependencies within a three-dimensional classification approach and investigates how interoperability and integration of metadata can be achieved based on a federated metadata architecture and standardization efforts such as OIM and CWM.
Abstract: In current data warehouse environments there is either no or only insufficient support for a consistent and comprehensive metadata management. Typically, a multitude of largely autonomous and heterogeneously organized repositories coexist. We categorize the major metadata types and their interdependencies within a three-dimensional classification approach. We then investigate how interoperability and integration of metadata can be achieved based on a federated metadata architecture and standardization efforts such as OIM and CWM. In particular, we examine synchronization alternatives to keep replicated metadata consistent. We also give an overview of currently available commercial repositories and discuss interoperability issues to couple data warehouses with information portals.
