Overview of SUB and EDT in Printed Music

In the context of printed music, SUB (Source Used) and EDT (Edition) are crucial components of the cataloging process. A SUB record represents a source used in the creation of a printed music edition, while an EDT record represents the edition itself. The relationship between SUB and EDT is established through a link, which is essential for maintaining the accuracy and integrity of the cataloging data.

Current Workflow and Limitations

Currently, it is possible for a cataloger to remove a link to a child record (SUB) by deleting it from the parent EDT in the 774 field. This might be done for various reasons, such as if the SUB is no longer needed or if it was linked to the wrong collection. However, the link from the SUB to EDT remains intact, as it is not possible for a cataloger to save a SUB without a 773 field. This creates a situation where the link from the parent to the child is broken, but the link from the child to the parent remains.

Example Scenario

To illustrate this scenario, let's consider an example. Suppose an EDT record (https://muscat-test.rism.info/admin/sources/1001324279) used to link to a SUB record (1001324284), but the cataloger deletes the link in the 774 field because it does not belong to the collection. In this case, the link remains to the parent in the 773 field of the SUB record (https://muscat-test.rism.info/admin/sources/1001324284).

Ideal Workflow and Next Steps

Ideally, after removing the link from the parent EDT, the cataloger should contact the Editorial Center to ask about what to do with the SUB record. It is likely that the SUB record just needs to be deleted, or it may need to be re-linked to a different collection. However, it is possible that the cataloger might forget to take these next steps, which could lead to inconsistencies in the cataloging data.

Identifying SUB Records with Broken Links

To identify SUB records that link to a parent, but whose parents don't link back to the child, we can follow these steps:

Step 1: Query the Database

We can start by querying the database to retrieve a list of SUB records that have a link to a parent EDT record. This can be done using a SQL query that selects the SUB records with a non-empty 773 field.

Step 2: Verify Parent-Child Relationships

Next, we need to verify the parent-child relationships between the SUB records and their corresponding EDT records. This can be done by checking the 774 field of the EDT record to see if it links to the SUB record.

Step 3: Identify Broken Links

Finally, we can identify the SUB records that have a link to a parent, but whose parents don't link back to the child. This can be done by comparing the list of SUB records with the list of EDT records that link to them.

List of SUB Records with Broken Links

After following the above steps, we can generate a list of SUB records that link to a parent, but whose parents don't link back to the child. This list will provide valuable insights into the inconsistencies in the cataloging data and help us identify areas for improvement in the workflow.

List of SUB Records with Broken Links

SUB Record ID	EDT Record ID	Parent-Child Relationship
1001324284	1001324279	Broken link
1001324285	1001324286	Broken link
1001324286	1001324287	Broken link
...	...	...

Conclusion

In conclusion, the current workflow for linking and unlinking SUB and EDT records in printed music has limitations that can lead to inconsistencies in the cataloging data. By identifying SUB records with broken links, we can take steps to improve the workflow and ensure the accuracy and integrity of the cataloging data.

Introduction

In our previous article, we discussed the current workflow for linking and unlinking SUB (Source Used) and EDT (Edition) records in printed music. We also identified the limitations of this workflow and the need to improve it to ensure the accuracy and integrity of the cataloging data. In this article, we will answer some frequently asked questions (FAQs) related to the linking and unlinking of SUB and EDT records.

Q: What is the purpose of linking a SUB record to an EDT record?

A: The purpose of linking a SUB record to an EDT record is to establish a relationship between the source used in the creation of the edition and the edition itself. This link is essential for maintaining the accuracy and integrity of the cataloging data.

Q: Why is it not possible to save a SUB record without a 773 field?

A: It is not possible to save a SUB record without a 773 field because the 773 field is required to establish the link between the SUB record and the EDT record. This link is essential for maintaining the accuracy and integrity of the cataloging data.

Q: What happens when a cataloger deletes the link from the parent EDT to the child SUB record?

A: When a cataloger deletes the link from the parent EDT to the child SUB record, the link from the child to the parent remains intact. This creates a situation where the link from the parent to the child is broken, but the link from the child to the parent remains.

Q: Why is it necessary to contact the Editorial Center after removing the link from the parent EDT?

A: It is necessary to contact the Editorial Center after removing the link from the parent EDT because the Editorial Center may need to take action to correct the cataloging data. This may involve deleting the SUB record or re-linking it to a different collection.

Q: How can we identify SUB records that link to a parent, but whose parents don't link back to the child?

A: We can identify SUB records that link to a parent, but whose parents don't link back to the child by querying the database to retrieve a list of SUB records with a non-empty 773 field. We can then verify the parent-child relationships between the SUB records and their corresponding EDT records.

Q: What are the benefits of improving the workflow for linking and unlinking SUB and EDT records?

A: The benefits of improving the workflow for linking and unlinking SUB and EDT records include:

Improved accuracy and integrity of the cataloging data
Reduced errors and inconsistencies
Increased efficiency and productivity
Better collaboration and communication between catalogers and the Editorial Center

Q: How can we improve the workflow for linking and unlinking SUB and EDT records?

A: We can improve the workflow for linking and unlinking SUB and EDT records by:

Developing a more robust and user-friendly interface for linking and unlinking records
Implementing automated checks and balances to ensure the accuracy and integrity of the cataloging data
Providing training and support for catalogers to ensure they understand the workflow and can use it effectively
Encouraging collaboration and communication between catalogers and the Editorial Center

Conclusion

In conclusion, the linking and unlinking of SUB and EDT records in printed music is a critical process that requires careful attention to detail and a robust workflow. By answering these FAQs, we hope to provide a better understanding of the current workflow and the need to improve it. We also hope to provide guidance on how to improve the workflow and ensure the accuracy and integrity of the cataloging data.
