Some will be one-off labels for things like context objects, documents, bundle and collections. Others will be turned into templates to use as input to label generation software.
The following instructions assume you have already downloaded the latest version of the PDS4 master schema or the specific version you're working with, if not the latest releaseand have added an XML Catalog entry to use it to define the PDS namespace, as described in Configuring XML Schema validation.

The example below uses a pre-release, beta-test version of the PDS4 master schema. Some of the details of the schema content you see might not be valid under official releases, but these details are not relevant to the process we're describing - so try to ignore them Here are the files I'm starting with in my "Demo" project.
Make sure the "parent folder" name above the center box is the one you want, and type in the name for the new file. Note that all XML label files should have an extension of ". You're presented with two options. Either way you'll end up in the same place, but here's how they work.
The first option is the Select file from Workspace option, which will let you select a schema. First thing to change is the Root elementshown as a pull-down list near the
Validating xml using xsd in eclipse. Select the specific product type from the list. Never use Label as the root element of your label.
Next come check boxes for Content options. I generally uncheck all of these, but that's my personal work preference. Once you've done a few of these, you'll develop some preferences of your own. Mainly it comes down to whether you want to add things to the minimal required set, or delete things from the set of all possible options.
Finally, we come to the Namespace Information box. I'm not a big fan of single-letter abbreviations and the PDS preference is for standardized namespace abbreviations, so I'm going to start by selecting the
Validating xml using xsd in eclipse that's showing and clicking the Edit This opens another dialogue in which you're only allowed to edit the prefix abbreviation.
This is also a personal preference - you could equally well change the "p" to "pds" in which case all the PDS4 element names will be prefixed with "pds: Now, if I also know I'll be referencing other name spaces, it's convenient to add their info here as well. The prefix will be the standard prefix for the SBN namespace, which is "sbn". Unfortunately, eclipse doesn't give you any auto-fill help with the actual namespace name, so you'll have to type it carefully. I've typed it in for the SBN namespace, below.
Finally, since locations are machine-specific and we don't actually want machine-specific information in archival labels and we're using the XML Catalog file entries to resolve namespace URIs to a physical file referencethe Location Hint: Note that each namespace must have a unique prefix, and only one namespace can be the default namespace i.
You can provide a prefix for all namespaces, if you like.
You can also change, add and delete additional namespaces and prefixes after you create the label, if needed although changing a prefix after you've added namespace elements can be an error-prone operation. Once you're done adding namespaces, click the Finish button and the skeleton of your new XML file will appear in your editor window, though there's still some toughing-up to do:.
Here I've added the instruction with a reference to

Note that the file extension for schematron files is. Whitespace inside tags is not significant, so adding line breaks and padding will not cause a problem but do make it easier for me to get the accounting right:. Here you can see the result of the namespace definition we did in creating the label - the PDS4 common namespace is identified and assigned no prefix; the SBN namespace is also present and is assigned the "sbn" prefix.
