Start with these questions and prepare your answers.
1. Why are metadata services important for digital libraries or collections? Give three reasons. For each reason given, use a specific example or context to support your assertion, and discuss the importance of metadata services in each case. Also create a row heading for reasons and a column heading of the examples. Fill in the corresponding table cells.
2. Which types of metadata services are used for different purposes? Create a table to list the types of metadata services in the row heading
and list the purposes in the column heading. Fill in the types and purposes in the corresponding table cells.
3. How will you register the schema you created for the chapters 4 and 5 exercises? Create a metadata description for your own schema
following the requirements listed in section 6.2.3.
4. How do metadata services facilitate information retrieval? Use a table to list the ways that metadata services facilitate information retrieval
and the technical requirements involved in the process. As with exercise 1, create a row heading of the ways to facilitate and a column
heading of the technical requirements, and fill in the corresponding table cells.
5. What do you think about LAM data as Linked Data? What are the basic concepts and perceptions that should be addressed? Taking any
metadata description or record you have created after chapter 3, highlight the entities that you think could become linkable points.
6. What are the major issues of findability of digitized materials? Identify an existing digital collection and provide a plan of three approaches
that should be put into action.
