Creating a work, instance, item
With Figure 1 shows the home page for the HipHop examplecollection VitroLib instance. From the home page, the cataloger can click the button that says “work” which will open up a form, shown in Figure 2, with fields that were included based on the “constant music record” macro or template that was identified by catalogers as relevant to this work.

This form creates the work, instance, and item and relates them to each other. At the work level, the cataloger can identify title, type, language, and lookup persons or organizations from the Library of Congress (LOC) Name Authorities or from ISNI. Clicking on the “verify this match” link next to the selected entity from LOC will open up the LOC page describing the Real World Object (RWO) to which we are linking this work.

Hitting save will take the cataloger to the resulting work page, shown in Figures 11, 12, and 13 .
Hitting save will take the cataloger to the resulting work page below, which shows the information they entered at the work level and will allow them to add more information or edit existing information.

The grouping and display of properties is governed by decisions captured in SHACL metadata application profiles for the HipHop use case. For some of these properties, we created custom editing forms that will enable the cataloger to specify multiple related pieces of information together. We We have also created custom displays which show more information than the default object label and link. For example, the physical instance or manifestation property provides a link from the work to the instance but also includes information about the instance such as publisher, date and location of publication, and audio issue number. Clicking on the name of the instance will take the cataloger to the linked instance entity shown in Figure 14. Next to the specific class of entity on work, instance, and item pages, we also display “work”, “instance”, or “item” to help identify the information the cataloger is viewing. The instance “audio example” thus shows “(instance)” next to the specific type “Audio disc”. Like the work page, the instance page has properties with information that the cataloger can view or edit. The “has item” property links to the item page which shows properties at the item level.

The architecture overview page discussing lookups explain how the custom forms for adding genre forms work, so here we will provide two different examples of custom forms. A work could have song contents and these can be added using the custom form shown below. In this form, the cataloger can pick a work already existing in VitroLib (as shown in Figure 18) or select the option to create a new work (as shown in Figure 19). They can also include information about an activity or role (e.g. composer) and a Library of Congress Genre Form term. The form thus enables adding many different relationships together. Once they have added the content listing, VitroLib will create the new work and provide a link to work under the content listing/track listing property (as shown in Figure 20). In this example, clicking the link takes the cataloger to the “song content” work page shown in Figure 21.

Another custom form example is that for adding a measurement group with separate measurements. In the ontology, the measurement group can be associated with multiple measurement entities where each measurement is associated with entities or values describing numeric value, unit, and dimension. The form below shows the fields for one of three possible measurements that can be added.
