Abstract: An online system uses a task async engine to coordinate task execution, such as for phased content creation, where the system enables content providers to efficiently create and publish sponsored content in multiple phases. Each phase of the content creation is represented by a draft of the content. Multiple drafts of the content are stored in a repository of the online system for optimizing content delivery and publication, such as quick identification of conflicts in a draft based on analysis of draft fragments of the draft. Objects associated with the sponsored content are stored in an object model. The connections amongst the various draft segments of a draft are stored in a hierarchy structure. Each user associated with a draft has a role, where all of the roles can contribute to the draft. The online system efficiently publishes the drafts and presents the sponsored content to its target users.

Abstract: A data structure with large amount of data is organized such that each entry is a data object having a plurality of indexing fields that contain derived data from data sources that are constantly updated. To update the data structure with minimal latency, a system retrieves data from the data sources and stores the data in indexing fields of a data object. To allow different users to modify their own draft versions of the data structure, the system stores the user's changes for each modified data object. Each user's own view is then generated by modifying the data structure based on the user's stored changes. The system pre-computes derived data for data objects by detecting changes in data sources and identifies which fields in the data structure were affected by changes. The system accesses logic for computing the derived data to update fields in the data structure.

Abstract: Structured metadata extraction may include accessing one or more documents from which to extract the structured metadata from each of a plurality of hosts. A plurality of entity names can be extracted from the one or more documents from one of the plurality of hosts using an entity name pattern. A first element list can be extracted from the one or more documents based at least in part on the plurality of entity names and based at least in part on one or more heuristic rules. An element list pattern may be generated based at least in part on the first element list, and a second element list may be extracted from the one or more documents based at least in part on the element list pattern.
