Abstract: A computer-implemented method includes receiving a search query that includes a user specified search criteria directed toward one field of a plurality of fields associated with a synonym group, and performing a search of a database of a scientific data information system based on the search query. In addition to the user specified search criteria, the search includes all of other the fields associated with the defined synonym group.

Abstract: A computer-implemented method that includes providing an authorized user with an option to define one more levels of a signature method, and providing the authorized user with an option to assign at least one user whose signature is required for each of the defined levels.

Abstract: Data information systems include memory for storing a first content item representing a predefined workflow. The first content item has a data format that complies with a unified data structure. The data information system further comprises a scientific instrument configured to acquire data in accordance with the predefined workflow, and a server in communication with the scientific instrument to obtain the data acquired by the scientific instrument. The server has a processor that executes program code to convert the acquired data into a second content item with a data format that complies with the unified data structure. The unified data structure can include an instance data element with fields that are specific to a type of content item, and a catalog data element having a copy of data extracted from the type-specific fields of the instance data element.
