Trying Out METSFlask

Overview

I will try out the following METSFlask.

It is described as follows:

A web application for human-friendly exploration of Archivematica METS files

Usage

You can try it on the following site.

http://bitarchivist.pythonanywhere.com/

Here is the result of uploading a METS file. In this case, since only one Word file was stored, information about one original file is displayed.

Clicking the View button navigates to the detail screen.

In PREMIS Events, the contents of the mets:digiprovMD section of the METS file were displayed. This section handles digital provenance metadata (information for tracking the origin and history of digital objects).

Here is an explanation of mets:mdWrap by ChatGPT 4:

The mets:mdWrap (Metadata Wrap) element is one of the XML elements used within the METS (Metadata Encoding and Transmission Standard) framework. METS is a standard for recording structural, administrative, and descriptive metadata of digital objects. This framework is widely used in digital libraries, archives, and museums for managing digital collections.

The mets:mdWrap element wraps specific types of metadata (e.g., descriptive metadata, administrative metadata, rights metadata, etc.) and is used to encode them within a METS document. This element is commonly used when metadata is directly encoded in XML format (inline), but it can also be used to reference external or binary metadata.

Within mets:mdWrap, the following important attributes and child elements may be included:

MDTYPE attribute: Specifies the type of wrapped metadata. Various metadata standards such as MODS, DC (Dublin Core), MARC, etc. can be specified.
MIMETYPE attribute: Specifies the MIME type of the metadata (mainly for external references or binary data).
LABEL attribute: Used to specify the label or title of the metadata section.
<xmlData> element: Contains inline-encoded XML metadata.
<binData> element: Contains binary-encoded metadata (for inline encoding of binary data).

By using mets:mdWrap, a METS document can flexibly handle and encode metadata in various formats and representations. This is essential for supporting comprehensive management and access of digital objects.

Additional Notes

The items listed in “File details” of the earlier visualization result display the contents of the following mets:amdSec.

“amdSec” refers to the “Administrative Metadata Section” within a METS document, containing copyright information, preservation metadata, and other administration-related information for digital objects.
