  1. Recalculate fixity SHA2 and insert into Rosetta

    We have around 22,000,000 files that we would like to recalculate a new fixity hash, but this time it would be SHA256. We need a good way of getting this fixity back into Rosetta. We would like to store it along with the SHA1 value we previously generated. We are aware that the SHA1 fixity is located in xml clob data in the hdemetadata table. We are wondering if there is another location for this SHA1 value in another table.

    • untangle format identification/validation/MDextraction

      In the course of the discussion on the "File Extension Mismatch - Change Notice" posted on BaseCamp by Opher Kutner (ExL), I noticed that some aspects of file identification/validation/MDextraction in Rosetta need improvement. What got me thinking was the statement that format identification was done by the extractor, which isn't the case. Instead, the actual behaviour is that the MdExtractionPlugin also does the format validation, while the format identification is run separately in DROID. However, the job of extractors is neither format identification nor format validation. Instead, it's metadata extraction only. Usually, a preservation repository can't even know which extractor…

      • IE Viewer enhancements

        Fist of all I like the looks of the new repository viewer and looking forward to the new IE viewer that Adi showed in the Rosetta 5.3 highlights webinar. There are a couple of things I would like to see in the new IE viewer, though:

        The new metadata panel looks great, but should be collapsible to make more room for the viewer panel. The same is true for the content panel.

        For some collections in Rosetta, no or hardly any descriptive metadata was available during ingest. The DC record for those IEs is typically empty except for a dc:title…

        • Search for "unknown" extensions

          It is currently not possible to search for files with extensions that are not recorded in the Format Library, such as .md or .cxml, because they are not included in the autocomplete list. So there is no way to build sets of files with such “unknown” extensions. According to Ex Libris, there is an open issue on this subject: DPS-16975. I would like to suggest that increased attention be given to this issue and that a solution be planned for one of the upcoming releases.

          • SRU request to get the file PID

            For a specific use case, we need to get the deep link of a file in Rosetta. Our idea is to use the SRU request for this purpose. But currently SRU requests only return IE-level responses, and not file-level information. We would like to see this changed and are asking for the option of a SRU response at file level to be added.

            • Ability to integrate our Ingest tool with Rosetta

              We are looking at supporting the ability to add a new format to our Ingest tool, in conjunction with this we would like that to trigger some type of API call to Rosetta and add the file format as an allowed format as well.

              In Rosetta you can add a new file extension in the Submission Format area of the UI. We have provided the option to add a new format in our Ingest tool, So once they do this, we would like this to trigger an some type of API call to Rosetta and add the new file extension…

              • Support the ability for Rosetta to request IEs in batches

                We would like Rosetta to work more efficiently when the storage layer is tape based, particularly for exports. Could Rosetta request IEs in batches from the storage layer. when exporting large collections from tape a file is retrieved from tape one at a time.

                  • Bitstream information in Bitstreams Tab

                    Researchers often use zip or tar files in order to upload large amounts of research data in various formats. Bytestream extraction is a useful tool for analyzing the content of these container files. The resulting bitstream information is written in the METS and displayed in the BitStreams Tab in the Web Editor. The information includes BS ID, file name, file original path, extension, mime type and format ID (if successfully identified).

                    We would like to suggest the following improvements for the BitStreams Tab and the bitstream information in general:

                    1) Include Bitstream size. The relevant values can be found in…

                    • Make IE Viewer share button configurable

                      The share button in the IE Viewer currently always shows the browser URL. Often the IE has an OID or some persistent URL that is preferred over the transient viewer URL. Rosetta should allow the URL that is displayed to be configurable. Preferably with an XSLT per institution similar to the IE metadata XSLT.

                      It is also desirable to allow for more than 1 URL in the share window. That would allow to add URLs for standalone vs embedded viewers, thumbnail view, CMS metadata view, etc.

                      • Rework/rewrite AIP update functionality

                        Since version 4, Rosetta includes a feature called AIP update. This feature is used mainly by libraries to alter data in the permanent repository, which might be necessary for a number of reasons. Metadata might need updating due to a typo or due to new research results, new files that weren't included in the original ingest might be added, or existing files might be altered with higher resolution versions or to repair defective files. Libraries tend to use this feature, because they regularly ingest SIPs that include a minimal set of metadata. Later, when full metadata have been allotted or…

                        • Upgrade internal XSLT processor

                          Currently Rosetta seems to accept only XSLT 1.0 syntax for XSLT configuration files. This means we are deprived of the many goodies of XSLT 2.0 and 3.0:

                          - strong typing and XSD types
                          - XPATH 2.0 sequences
                          - XSL functions
                          - range variables
                          - regular expression matching and grouping
                          - URL encoding and decoding
                          - better value comparison

                          EXSLT 1.0 is not supported either, so whenever I try to do something more intelligent that some simple markup and string replacing, I hit the limits of XSLT 1.0. Trying to make decisions in your XSLT based on element values without regular…

                          • Allow institutional parameters for (custom) plugins

                            In a consortial landscape a plugin may be used by several institutions. However, each institution may need to use different parameters for a shared plugin.

                            To give examples, consider these two business cases:
                            (1) A plugin utililzes proprietary 3rd party software that is licenced per institution. In such case we must ensure that only the institutions that actually pay the licence fee have access to the functionality. The license key would have to be configured per institution.
                            (2) A PDF migration plugin can take different input parameters which determine the output format to be created (e.g. to PDF/A-1b vs. PDF/A-2b).…

                              Here at SLUB, we're seeing a few issues with the way indexing is implemented in Rosetta.
                              Currently, all Rosetta servers that are in the "Indexer" role hold a single part of the whole index with no redundancy between the indexing nodes. If there's an outage in one of the servers, there are two effects.
                              N°1: One third of the index entries will not be available and the missing server will not take part in indexing any new IEs, obviously. The IE that was just being processed by this server will not be in the index and information about it will…

                              • Take account of the METS mimetype attribute during file ingest

                                The METS standard has a mimetype attribute on files "<file MIMETYPE="application/pdf" ... /> but this information is currently ignored by Rosetta during the file-type identification process on ingest.

                                Mimetye should be at least as reliable as file extensions (because mimetype is a standard, is actively maintained and widely use by a good portion of software for identifying file types).

                                In particular, recognising mimetypes is likely to greatly increase the ease of ingest of content from internet-facing content management systems where it is very widely used

                                • view only- user who cannot break anything

                                  For error-detection and workflow documentation it is sometimes necessary to be able to view all configurations in Rosetta - even all in the Administration area.
                                  But not all users should be able to edit configuration elements in Rosetta, especially not in the Administration Area.
                                  In our (ZBW/Germany) opinion, a view-only-user would be very handy. This person would be able to see all the configuration details and the view-option would be available to her/him, but not the edit-button.
                                  She/he would not be able to break anything, but would be able to see all the details needed for documentation or other purposes. …

                                    After experiencing some problems with Rosetta's Format Library update mechanism (see SC 00423700 "error while updating Format Library [Rosetta 5.1.0.2]", handled by Paul), we got thinking about Rosetta updates in general. Currently, all updates are downloaded through an unencrypted connection. This includes:
                                    - Rosetta updates (major, minor, service packs, hotfixes) and their checksum files (!)
                                    - Oracle updates and their checksum files
                                    - PDS updates (presumably)
                                    - Format Library updates
                                    Due to this, there's no way to verify authenticity of ExLibris' servers and the integrity of the update packages/the checksums. All information that are downloaded from ExLibris' servers must be…

                                    • In Material Flows: remove option to "automatically extract compressed files" when the Content Structure is changed to METS

                                      The material flow configuration includes the default option to "automatically extract compressed files". This option works in all workflows except METS content structure work flows, as extracting compressed files leads to mismatches in the METS struct map.
                                      Material flow configuration screens should blend out the extraction option for METS content structure or make the user aware of a faulty configuration upon saving such a combination.

                                      • provide Rosetta developer previews

                                        ExLibris' current mode of releasing new Rosetta versions is to announce a rough time slot ("April this year") for that new version/minor-release/servicepack/hotfix, release it and deliver a list of changes along with the new release. Up until the actual release, ExLibris will only give a very general roadmap of the planned changes. While this is an easy approach for ExLibris, it's hard for the customers to prepare for the release. Therefore, I propose for ExLibris to provide pre-release versions of Rosetta in order to enable developers to adapt their software (i.e. Submission Applications) to new features, changed API behaviour etc.…

                                        • relative paths in IE XML / Storage Migration

                                          Rosetta 5.2 has brought a new Storage Migration feature that enables institutions to restructure their permanent storage to fit changing requirements. However, the documentation currently warns that "Disconnecting legacy storage is not recommended as it may prevent the possibility of reverting to a previous IE version." (https://knowledge.exlibrisgroup.com/Rosetta/Product_Documentation/Version_5.2, Preservation Guide, page 185). As far as I can see, this limitation is due to the use of absolute paths in the IE XML files. The paths in older versions of these files cannot be updated without forging provenance information, which, of course, isn't an alternative. However, updating these paths would…
