CollectiveAccess can be configured to automatically choose one over the other for specific file types, or to let the user decide which to use. Therefore you may wish to employ ExifTool for some types of media and MediaInfo for others. ExifTool returns comprehensive data for images, but may not capture all aspects of time-based media. MediaInfo is an excellent tool for extracting embedded descriptive and technical metadata from audio and video files, but returns limited metadata for images and documents. Creation of mappings for the import of output from these tools into CollectiveAccess is described in detail below. When using ExifTool, data is presented as nested value tags. When using MediaInfo, extracted metadata is presented for import as PBCore version 2.0 XML. Crosswalks between embedded metadata extracted from media and CollectiveAccess records are specified using the same import mapping format used for general data import.ĭata is extracted from media using the standard MediaInfo and ExifTool applications. Transformation and import of media embedded metadata employs the import system used for import of data files in various XML and delimited file formats. Import of embedded metadata can be performed on media uploaded as object representations individually in the record editor interface or in batches using the media importer. CollectiveAccess can extract and import EXIF, IPTC, XMP and technical metadata embedded in uploaded image, video, audio and document files.
