Media, which is often an important component of a record, can be tedious to upload file by file. Fortunately, CollectiveAccess offers a Batch Import tool to simplify the upload of large sets of files. In this section, we will look at each element on the Media Batch Import screen. To use this tool, click on "Import" in the Global Navigation Bar (see below):
Before you begin importing media, you must carefully define your settings. Begin by choosing a directory to import from the top field on the screen. Click on the grey arrow to the right of each directory name to display a list of the folder's contents. If the folder includes subdirectories containing media you wish to import, be sure to check "Include all sub-directories" at the bottom of the field. This option will remain checked the next time you perform an import unless you choose to uncheck it.
Next, you must choose an Import Mode. In the second field on the screen, you will see a drop-down list with three options: "Import all media, matching with existing records where possible," "Import only media that can be matched with existing records," or "Import all media, creating new records for each." Let's take a look at each of these options.
1.) Import all media, matching with existing records where possible: Choose this option if you know that you already have some records in your system with object identifiers that correspond with the filenames of media in your import. CollectiveAccess will search for these matches and thereby avoid information duplication. Any files that do not match an existing record will be turned into new records, and you will be responsible for fleshing out their contents.
2.) Import only media that can be matched with existing records: Choose this option if you do not wish to create any records beyond those already in place. CollectiveAccess will import files that match existing object identifiers, and no others.
3.) Import all media, creating new records for each: Choose this option if you have no pre-existing records in the database, or if you know that none of the pre-existing records match the media you're importing. You will then have barebones records for each file in your import, and you will need to complete those records by hand.
The next field in the batch-import interface asks you to specify Type. As we have discussed, every record in CollectiveAccess has a Primary Type, and certain types of records are further divided into subtypes. A batched media import will apply to Object records, so you must choose the subtype that applies to your media. For example, are they all photographs? Documents? Postcards? It is important to note here that in order to perform a batch-import, you must be sure that all of the media you are importing are of the same type. In other words, group the files together in a systematic way before beginning to upload them. The Type field on the Batch-Import screen has two drop-down lists: 1.) Type used for newly created objects: As discussed above, you must choose the type of object record to be used for your media. Some systems will have more nuanced choices than others, but make sure all of the media you're importing in one batch is of the same type.
2.) Type used for newly created object representations: This drop-down list has three options: Front, Back, or Default. Choose front or back when you are importing a batch of media that could have multiple representations. A batch of images of postcards, for example, may have views of either the front or back of the object in question. Otherwise, choose default.
