# Provenance Information For an specific data object there are likely to be many "siblings" with similar histories, but the most recent activities will be unique to that object. The Provenance information would initially be relatively simple until information from multiple sources are combined e.g. a FITS image for an area of the sky in one wavelength combined with similar images for other wavelengths. Handling such Provenance is still an area of active research see and . There are multiple methods in use to capture Provenance, often dependent on the domain. For example the library community often use PREMIS, which can be associated with specific vocabularies. Open Provenance Model (OPM, ) and PROV () are available standards. Many scientific formats contain elements of Provenance, for example FITS files have COMMENT and HISTORY records which can be used to describe the data unit and its provenance, while [HDF ](https://www.hdfgroup.org/solutions/hdf5/)can also contain customized Provenance. In such cases the way in which the Provenance is encoded may be specific to a particular project and specific code would be required to extract it, perhaps into one of the standard formats to allow efficient queries to be performed. Where the Provenence, or part of it, is encoded within the Data Object, as with FITS or HDF, the Provenance Information should describe how to extract that (piece of) the Provenance and its Representation Information, such as its Semantic RepInfo. The Provenance Information may be encoded as a separate Data Object, for example PREMIS, OPM etc, and therefore there must be associated Representation Information for that object, for example the definition of the version of PREMIS and specific vocabulary used. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.libnova.com/labdrive/data-curation-and-preservation-1/how-to-deal-with-additional-information/provenance-information.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
