Devise a local metadata element set based on the characteristics and requirements of five digital artifacts in your graduate educational portfolio. Using your local scheme, create descriptive metadata records for the artifacts and apply controlled vocabulary and syntax standards to the element values.
Study the Dublin Core scheme and structure, including the semantic meanings of the elements, and create a crosswalk document showing how you would map data between the local element set and Dublin Core.
Identify and discuss issues related to creating local metadata and to mapping from one scheme to another.
Assignment Steps
1-Review your graduate educational portfolio and select five digital artifacts for which you will create metadata records. These artifacts can be from any graduate program.
2-In any combination, the artifacts must meet the following criteria:
*One artifact must be the product of multiple contributors (e.g., PowerPoint or Prezi group project).
* One artifact must have a Table of Contents (e.g., research paper or report).
* One artifact must be part of a larger project or collection (e.g., PowerPoint file from presentation).
3-Based on the features of these artifacts, develop an original, comprehensive element set that captures as much information as possible about your resources. This local scheme should include, but is not limited to, the resource identification and responsibility elements addressed in Miller chapter 3 and the content and relationship elements discussed in chapter 4.
4-A sample Excel file is provided. Use it as a template or create your own spreadsheet file that contains three worksheets:
Sheet 1: Local Scheme: Create a 3-column table listing the elements of your local metadata scheme, a brief definition for each element, and any vocabulary or syntax encoding scheme required for that element.
Sheet 2: Metadata Records: List the data elements of your scheme as column headers and below enter the values for each of the five metadata records as rows (i.e., one row for each artifact = six rows total).
Sheet 3: Metadata Crosswalk: Study the Dublin Core scheme and structure, including refinements, and create a crosswalk document showing how you would map data between the local element set and Dublin Core. The table should include the local element, the DC term, and any implementation notes that describe how data has been combined or omitted. You may not be able to bring all the data and context from the local scheme into DC without losing data. One purpose of this assignment is to get you to think about the decisions that you are making in what data is mapped and what data isn’t.
5-Write a short report that describes your experience of doing this assignment. The structure of your report should include the following sections:
Introduction: Briefly introduce the document, your local metadata scheme, and each of the five artifacts you created descriptive metadata for.
Discussion: Analyze the issues that arose when creating your local scheme and records and when mapping the scheme to Dublin Core. You can discuss such areas as the functional requirements of your artifacts, the quality of the metadata, encoding decisions, challenges of the mapping process, and so on. To me, this analysis demonstrates your learning process and your understanding of the issues as they relate to the principles covered in the course readings, so spend some thoughtful time on this.
