Writes metadata from the selected records back to the related assets or metadata container, e.g. XMP files. Opens a dialog to specify an appropriate Asset Handling Set and optionally to select the metadata fields that should be written back. (Disabled if no Asset Handling Set is available that has enabled the writing back metadata option.)
When writing back metadata to assets, be aware of the following:
• Metadata can be written back to assets only
• if the assets are not write protected or stored on a write protected volume or media.
• if Cumulus has direct access to the assets (no Server/Client Asset Transfer).
• Some IPTC and XMP metadata fields overlap. All assets that have been edited with applications of the Adobe Creative Suite contain both IPTC and XMP metadata. When writing back metadata to such assets, make sure that both the Cumulus IPTC and the XMP filter are activated. If not, the IPTC and XMP data stored in the asset might differ.
NOTE: Captured IPTC and XMP metadata As some image files contain IPTC as well XMP metadata in different blocks, and some metadata information is stored in both blocks, the metadata captured by different applications might differ. Some applications give priority to XMP (e.g. Adobe Creative Suite). With a standard installation, Cumulus captures IPTC metadata prior to XMP. If you want to alter the priority to XMP, you have to change the order of the formats for the Asset Handling Set employed for cataloging. In the Asset Formats list of the Asset Handling Set, the entry for the Extensible Metadata Platform format supported by the XMP filter has to have a lower entry number than the first format supported by the IPTC filter. This is due to the fact that Cumulus starts searching for matching formats at the lowest entry number. (see Asset Format Support, for further details.)
NOTE: Metadata size restrictions in JPEG assets The size of meta data fields in JPEG files (e.g., EXIF data or XMP data) is restricted to 64 kB. However, metadata larger than 64 kB can be written back to the JPEG file and is saved in discrete segments of 64 kB each. Although this is conform to the specification, keep in mind that not every image editor / JPEG readers is able to read large metadata properly!
NOTE: Writing back keyword categories to assets In order write back keywords from the $Keywords master category to assets (e.g. to have these keywords available in other applications), make sure that field linking “when writing back metadata” is activated for the “Categories” record field, but is disabled for the “Keywords” record field (via Field Properties > Field Linking tab for each field).
