If the field in question is a list-type field, the Tag on Import rules can add values to the ones defined in the JRSidecar files, but if there is a conflict between the two, the sidecar data always "wins". Tag on Import rules will not overwrite fields that are filled explicitly by a JRSidecar.xml file (if these are enabled and already exist). This rule changes any file already tagged "NCISLA" to "NCIS Los Angeles" instead, which allows it to be found automatically on theTVDB. This is useful because it allows you to "massage" the needed fields (such as the field) for files which otherwise wouldn't be looked up properly. The only major step of Importing that is not done before Tag on Import rules are run is the Automatic Metadata Lookup system (which downloads metadata for TV Shows and Movies from online databases). This means that you can count on all normally filled tags to already be filled before these rules are applied, including filename parsing done by Carnac and reading any embedded file tags (and information stored in JRSidecar.xml files if enabled). If you import files by drag-and-drop or via the Windows Explorer Shell Extensions, any Tag on Import rules you've defined in your Auto-Import settings are not applied.ĭuring the Import process, Tag on Import rules are run after all other parsing and analysis Media Center does as part of importing the file. Also, as is noted above, Tag on Import rules are only applied when when files are imported via the Auto-Import and Television recording systems. If you want to tag files you've already imported, you need to tag those manually, and your Tag on Import rule will apply to new files you import in the future. They do not run continuously on files that are already in your Library. Tag on Import rules are only applied when files are first Imported. If not, just pass through the pre-existing value (so you don't overwrite anything already there). Look at the value of some existing field (such as or something else that you know will already have a good value) and then if it matches the result you want, apply the particular value. You can usually use simple expressions following this pattern to apply tags to only certain files in the import folder. So, to accomplish the example given above, you check to see if tag already contains "Dora the Explorer", and then apply the tag if it does. This is actually easy to do! The Value field in the Tag on Import rule dialog can be set to an Expression, using any of the features of the expression language. For example, you might want to set the to "Kids" only if the file imported is an episode of Dora the Explorer. However, it is often useful to apply a value to the field only conditionally based on some other characteristic of the file. This is occasionally useful if the folder in question contains only certain types of files. The simplest Tag on Import rules apply the exact same tag value to every file imported from the selected folder. If you add a Tag on Import rule that applies a value to a List Type field, such as or, the value will be added to any existing value rather than replacing the value already there (from an embedded ID3 tag, for example).
