1. Lifecycle Metadata for Digital Objects November 13, 2002 Rights Management Metadata

2. What is Rights Management? Protection of copyright Protection of patent Protection of the integrity of the digital object (and thereby reputation of the author/creator herself)

3. What is being protected? Object itself (integrity) Uses of the object (access controls) –Limiting use (protecting rights of the owner) –Enabling use (protecting rights of the user)

4. Protecting against outright theft Example: “Operation Buccaneer” Security elements added to the object Capture object (inside job) Crack/remove protections Test Repackage for distribution Distribute

5. Protection against theft Threats of the law Fully document with metadata and protect the metadata Authentication of users and user requests Watermarking/steganography

6. What about integrity of the digital object? Relevant even in public domain E.g. “copyleft” agreement: http://www.gnu.org/copyleft/gpl.txt http://www.gnu.org/copyleft/gpl.txt See but not change, or change only with notification

7. Rights management metadata for copyright (DMCA) Identify object Identify creator Identify owner of rights Identify terms and conditions of use Pointers to details Other stuff per Copyright office

8. Rights possession metadata for the user Personal identification –Authentication schemes –Digital signature Institutional identification –Web of trust –Certification

9. Automating everything: elaboration on the OAIS access module User’s authentication authority Database of rights protection requirements for objects Repository authentication authority checks one against the other Request is allowed or denied

10. And now for something completely different Student webpages: a few remarks

11. Pathfinder/webpage structure Cover page Essay on domain Metadata set DTD sample XML document Annotated bibliography on domain Please separate your work in this way so that a uniform structure can be imposed on all the pages afterwards

12. Domain essay  Major problems it must solve  Definition of the domain  Evaluation of major relevant metadata initiatives  Justification of choice of elements as best solving domain problems

13. Metadata set Detailed description of elements so it is possible to tell which ones are the same Can be tabular or element by element; both forms can help clarity –element by element to present detailed description, cite comparative sources –tabular for a summary

14. Coping with a fragmentary DTD in your samples Each domain supplies only part of the DTD Therefore you need some way to do without the rest of it and just focus on your domain elements Use an external parameter entity thus: To refer to the batch of all elements other than yours within the DTD, use: %completeDTD;

15. XML document Be sure that you have validated your document against your DTD

16. Target objects The objects to which your core document should be able to refer are: –Text –Webpage –Still image –Database

17. What is an annotated bibliography? A list of the most important resources on the subject of interest, with full citation Annotated with a clear description of the contents of the source: You describe it—don’t just get a blurb from somewhere For our purposes the annotation should include what YOU think about the source and why you found it useful or why it is totally useless

18. Now for something else completely different XML/DTD hints

19. Testing your DTD inline Remember that your DTD can be included in your XML document “inline,” or included within square brackets as part of the DOCTYPE declaration Thus once your XML document validates, you can create a separate file for your DTD and refer to it in the DOCTYPE declaration For a simple example, see http://www.w3schools.com/dtd/dtd_intro.asp

20. Using Cooktop for XML To begin editing your XML document, use File, New—then choose XML Cooktop for the editor You can then proceed to write your XML document You can create tag pairs by using ctrl-2 to create a box, into which you type your tag name (without brackets); when you press enter, the program will make a pair of tags for you To see the structure of the document, use ctrl-3

21. Using Cooktop for DTD If you choose the DTD editor, you will simply get an ASCII editor for typing in your DTD Save it in the same directory and you only need to refer to it by the filename
