3. The system of claim 1 , wherein the subset of the collection of correlated data is related to a launched application that is part of the current user activity associated with the core document.
1. A computer-implemented system that facilitates data handling, the computer-implemented system having a processing unit executing computer-executable components stored in memory comprising: a data component associated with a datastore of the computer-implemented system that stores a collection of document data catalogs for providing a comprehensive collection of correlated data, the document data catalogs comprising data elements obtained from existing documents, wherein: an existing document is decomposed into a document data catalog for the existing document of corresponding data elements of the existing document according to one or more document templates defining a structure of the data elements of the existing document, each corresponding data element of the document data catalog for the existing document comprises a subset of data included in the existing document, the document data catalog for the existing document includes element metadata for each of the corresponding data elements of the document data catalog for the existing document, the element metadata for each corresponding data element of the document data catalog for the existing document is based on past user interaction with the existing document, and the element metadata for the corresponding data elements of the document data catalog for the existing document defines data element relationships and attributes for correlating the corresponding data elements of the document data catalog for the existing document to related data elements of related document data catalogs for different existing documents; a data selection component for automatically selecting and elevating a subset of the collection of correlated data based in part on current user activity associated with a core document by: selecting a core document data catalog for the core document from the collection of data catalogs and elevating, to a presentation surface, one or more relevant data elements of the core document data catalog based on the element metadata for the corresponding data elements of the core document data catalog in order to display one or more subsets of data included in the core document that are relevant to the current user activity associated with the core document, wherein the element metadata for the corresponding data elements of the core document data catalog is based on past user interaction with the core document, and selecting one or more related document data catalogs for different existing documents from the collection of data catalogs and elevating, to the presentation surface, one or more related data elements of the one or more related document data catalogs based on the element metadata for the one or more relevant data elements of the core document data catalog in order to display one or more subsets of data included in the different existing documents that are related to the one or more subsets of data that are relevant to the current user activity associated with the core document, wherein the element metadata for the one or more relevant data elements of the core document data catalog defines data element relationships and attributes for correlating the one or more relevant data elements of the core document data catalog to the one or more related data elements of the one or more related document data catalogs for the different existing documents; and an interface component for receiving and dynamically presenting the subset of the collection of correlated data in a user interface, wherein the interface component: displays the one or more subsets of data included in the core document that are relevant to the current user activity associated with the core document and the one or more subsets of data included in the different existing documents that are related to the one or more subsets of data that are relevant to the current user activity associated with the core document, and enables editing by a user of the one or more subsets of data included in the core document that are relevant to the current user activity associated with the core document and the one or more subsets of data included in the different existing documents that are related to the one or more subsets of data that are relevant to the current user activity associated with the core document for updating the core document and the different existing documents.
