Metadata

“What is metadata? Some sci-fi word? A collection of misplaced letters? No. The truth is, metadata is your friend. It could be your best friend if you choose and, most of the

time, its free to use!”

● Participate and contribute back to a larger community

● Metadata sharing is simplified as is system interoperability

● Leverage existing tools○ data dictionaries

Descriptive Metadata

Descriptive metadata is what authorized users typically add/edit within the Islandora framework. eg. MODS, DC, PBCore, DarwinCore and more.

Many elements have attributes that can be added.

Postcards

Use controlled vocabularies / thesauri where possible.

What is the XML Form builder

● A tool for creating/storing HTML forms that can create/manipulate XML Documents.

● A low level API for processing Form Definitions.

● A GUI build with Ext-JS that aids in creating Form Definitions.

What are the main features of the XML Form BuilderWorks with most standards, wanna share?

● Will work with custom standards.● Highly configurable.● Forms are portable.● Safe.● Built upon the existing Drupal Form API

MODS PBCore FGDC MADS

LIDO Darwin Core Dublin Core etc...

How do I use the Form builder?

Form definitions are essentially about XPath.

ExamplesCheat Sheet

A good tool to help you work with XML XSLT's and XPath is Oxygen!

CRUD (Create, Read, Update, Delete)

More CRUD

Read: Populate the form fields, set the "self" context.Update:The element/attribute exists, use the value in the form field to updated it.Delete:Only executed if the form field is removed.

Create a DC Collection Form

Lets create a DC form for the Collection Content Model

Root element …

Add dc:title element …

Add dc:title element …

That’s the pattern we’ll follow...

1. copy the title element we just created2. Select the Root element3. Select Paste and then update the

element information.

Save & Preview

Enter test data.

Now add a dc:type element. It is a controlled vocabulary so we’ll add that as a Select form element. Get the terms from http://dublincore.org/usage/terms/dcmitype/#H7 .

DC Types● Collection● Dataset● Event● Image● InteractiveResource● MovingImage● PhysicalObject● Service● Software● Sound● StillImage● Text

Select Add, then create the Value and Label for each type. Select Update after adding each type. If you start with the last term first it saves on having to sort the terms.

Your record can have multiple types … you can use tab panels.

Tabs ● Read

Tab Panels ● Create● Read● Delete

Text Field● Read● Update

Form building Best Practices!

● Prefer Parent context for both Create and Read.

● Prefer Self context for Update and Delete.

● Have the hierarchy of form fields match the XML document it creates.
