In response to receiving a change to one of the content data and the content metadata, a provenance value is calculated based on the change, wherein the provenance value represents a change in content between the changed content data or the content metadata and an original version of the content data or the content metadata, and a lineage value is calculated based on the change, wherein the lineage value represents a change in authorship between the changed content data or the content metadata and the original version of the content data or the content metadata. It is determined whether the calculated provenance value violates at least one constraint. It is determined whether the calculated lineage value violates at least one constraint.

Abstract: A database server receives a request from a client application for performing a data transaction on persistent data storage. The request is sent to a set of replication servers. An acknowledgement for the request is received from each replication server, including a start sequence number and an end sequence number for data that is stored in local cache of the replication server, and a latest committed sequence number for data that was written to the persistent data storage by the replication server. A maximum value of latest committed sequence numbers received from the set of replication servers is determined. For each replication server, it is examined whether there is a gap between the start sequence number for data stored in local cache and the maximum value of the latest committed sequence numbers. Based on the examining, it is determined whether there is an occurrence of loss of data.

Abstract: According to one aspect of systems and methods for dynamic recreation of multidimensional analytical data, lost sets of calculation scenarios that provide multidimensional analytical data results after aggregations and transformations of the multidimensional analytical data are recreated in the volatile storage of an in-memory computing engine. A multidimensional analytical data view (MDAV) compiler is triggered to read the MDAV metadata stored in an intermediate buffer in the MDAV compiler. The read MDAV metadata is compiled into a calculation scenario including calculation view metadata. The calculation view metadata is stored in the intermediate buffer. The recreated set of calculation scenarios is deployed on the in-memory computing engine.

The method further includes receiving a number of the communities to find within the social graph, receiving data regarding propagation of information between the nodes, and calculating a probability of formation of a link between a first one of the nodes and a second one of the nodes based on the data. The link provides a direction of flow of media between the first and second nodes. The method includes calculating a probability that media will be accessed by the second node based on the data. One of the communities includes the first node, the second node, and the link.

Abstract: Various embodiments provide a method of managing and preventing conflicted copies of a content item. For example, as changes are made to a content item, either by multiple users simultaneously or by a single user utilizing multiple devices, conflicted copies can be inadvertently created. These conflicted copes are multiple copies of the same content item where each copy may separately contain unique changes. Heuristics can be used to help users more easily avoid or manage these conflicted copies. In one example, a user could be notified and shown the difference between copies to either accept or reject changes. Further, users could also be notified when modifying a content item on a device that has not been synchronized in a determined period of time, or when the content item is known to be modified but the changes have yet to be synchronized to the device.

Abstract: A method for managing storage functions in a data replication environment is disclosed. In one embodiment, such a method includes continually monitoring for changes to a storage configuration at a secondary site. Upon detecting changes to the storage configuration at the secondary site, the method transmits remote metadata describing the changes to the primary site and stores the remote metadata at the primary site. The method then initiates a storage management function at the primary site which is mirrored to the secondary site. In order to perform the storage management function, the method reads the remote metadata at the primary site to determine the storage configuration at the secondary site. The method then performs the storage management function at the primary site in a way that takes into account the storage configuration at the secondary site. A corresponding apparatus, system, and computer-readable medium are also disclosed and claimed herein.

Abstract: Embodiments are directed to implementing locale-based sorting and to creating temporary metadata sorting values. In one scenario, a computer system sends a request for a contact list, where the request includes an indication of the user's locale. The contact list includes contact information for contacts of a specified user. The computer system receives the requested contact list, which includes various portions of appended, locale-specific sorting metadata for at least one of the user's contacts' fields. The computer system then sorts the contacts of the contact list according to the selected sorting criterion using the sorting metadata, where the sorting metadata includes a sorting order specific to the user's locale. After the contacts are sorted, the computer system presents the sorted contacts to the user in a user interface.

Abstract: Implementations and techniques for determining a relative importance among ordered lists are generally discussed.
