1. Open any Microsoft Word document and add metadata descriptions.

Instructions: Choose File Properties, then fill in the template provided in the Summary and Custom windows.
(To complete this exercise, Microsoft Word software is needed.)

2. Open a PDF file and add metadata descriptions.

Instructions: Choose File Document Properties and fill in values. Also try Additional Metadata and Advanced and explore different schemes of properties.
(To complete this exercise, Adobe Acrobat software is needed.)

3. Open an image from Adobe Photoshop or Adobe Bridge and add metadata descriptions.

Instructions for CS5:
–– Option 1: Open the image form by choosing File Browse (or Browse in Bridge). Select an image to preview and add metadata.
–– Option 2: Choose File File Info and fill in values in the Description template.
This is the same process as using an Adobe Acrobat for PDF files. After adding the metadata statements, choose Edit --> Find and set search criteria to find the image you just described.
(To complete this exercise, Adobe Photoshop CS software is needed. Note that different versions of CS may perform slightly differently.)

4. Use the DC-template provided by the book's web site to create a metadata description.

(1) Go to http://metadataetc.org/dctemplate.html, enter the data value in each field and submit.
(2) Choose to see the output in Preview mode or in HTML or XML format. You may copy any version of the output into a separate WORD or HTML file.
(3) Analyze descriptions based on section 3.7.2's explanations.

5. Create metadata descriptions using CONTENTdm.

(To complete this exercise, a CONTENTdm client and an account are needed. Go to www.oclc.org/en-US/contentdm/ordering.html for a free 60-day hosted trial or a full evaluation copy.)

6. Create a VRA XML record using oXygen software.

(To complete this exercise, an oXygen client and a license are needed. Go to www.oxygenxml.com/ to obtain a free 30-day trial license.)
