A system for resolving conflicts between data source updates and user edits to an ontology before applying the resulting changes to the ontology and related methods are disclosed. The system is programmed to receive data source updates from data sources and transform the data source updates to updates to ontology data. The system is also programmed to receive edits to ontology data from user accounts. The system is programmed to review these updates or edits to the ontology and resolve conflicts according to a predetermined strategy, such as prioritizing a user edit over a data source update. The resulting changes are incorporated to one or more databases where representations of the ontology data are stored.

Resolving conflicts between data source updates and user edits to ontology data

A system for enabling granular access control over ontology data and related methods are disclosed. The system is programmed to receive data source updates from data sources having respective sets of permissions for access control, transform the data source updates to changes to an ontology, and control access to the ontology based on the sets of permissions. The system is further programmed to receive a specification of one or more rules referencing attributes of user accounts or properties of ontology entities and corresponding one or more lists of permissions. The system is programmed to then enforce a security policy based on the specification to further control access to the ontology.

Fine-grained permission models for ontology data

Systems and methods are provided for performing constraint driven database searching. At least one constraint is received for a search of one or more databases comprising one or more datasets, each comprising multiple entry fields. The one or more databases comprising the one or more datasets may be accessed and searched based on the constraint to identify one or more dataset entries that contain the at least one constraint in one of multiple entry fields. A visual representation of the identified dataset entries may be provided to the user as results of the constraint driven database search. Additional constraints may be accepted to further narrow the results of constraint driven database search. The results may be exported and made accessible for later retrieval and/or cached for use in subsequent searches.

Systems and methods for constraint driven database searching

Methods, systems, and apparatus, including computer programs encoded on computer storage media for data synchronization are provided. One of the methods includes: receiving, from a client device displaying a spreadsheet interface, a query for data; identifying, from one or more datasets in a data store, a plurality of data items responsive to the query; sending, to the client device, a plurality of data entries for display in a plurality of cells of the spreadsheet interface, wherein the data entries correspond to the identified data items; receiving, from the client device, information associated with one or more changes to one or more of the data entries, wherein the one or more changes are created based on one or more user inputs in the spreadsheet interface; and updating, in the data store based on the one or more changes, one or more of the data items corresponding to the one or more changed data entries.
