Mermaid diagram software for query documentation | Stefan | https://mermaid-js.github.io/mermaid/#/ "Mermaid" or "Mermaid.js" under MIT license, so open source program can copy the program from GitHub can use the program to create graphics and diagrams using short scripts good opportunity to document derived table - don't have to create graphics with graphic program, just type in script and the program generates the diagrams automatically can create flow charts, sequence diagrams, gantt diagrams, class diagrams, entity relationship diagrams can use it as a command line interface program, but can also use the API by adding a script to your HTML document (API is probably better than command line, has more diagrams) Also a live editor: https://mermaid-js.github.io/mermaid-live-editor (no installation required) after adding JS files to HTML, just need to create a div with the class "mermaid" similar tools: could manage all of this on github documentation for ER diagrams: https://mermaid-js.github.io/mermaid/#/entityRelationshipDiagram what could we use this for? how is this different from SchemaSpy could it be automated? should we be really trying to prioritize this work? where to host the diagrams? confluence vs. GitHub? possibility for automation: https://dev.to/sualeh/how-to-generate-mermaid-diagrams-for-your-database-33bn

Updates and Query Demonstrations from Various Reporting Related Groups and Efforts | Community & Coordination, Reporting Subgroup Leads | Project updates Reporting development is using small subgroups to address priorities and complete work on report queries. Each week, these groups will share reports/queries with the Reporting SIG. Reporting development team leads are encouraged to enter a summary of their work group activities below. RA/UM Working Group Getting back into query writing, will talk soon about whether to focus on metadb or keep going with new LDP queries Angela will begin attending RA SIG meetings every two weeks or so to open the lines of communication Context
MM Working Group At our last lab session, We saw Cornell's HathiTrust report for serials. The entire process used 9 temporary tables to final create the final report. Data was being pulled from MARC SRS records. A lot of exceptions had to be taken into account. One issue raised about the template queries for the community was that institutions implement metadata slightly differently. Those in metadata tend to want to see institutional reports rather than templates to see how someone else ran the report and to get ideas on how to implement local metadata practices. We helped out with a query to get back a range of instance HRIDs that had an error. The query that needed help was pulling the instance HRID from the public.srs.marctab (SM) as an integer using this where SM.instance.hrid :: INTEGER between '15077113' and '15077535'. This worked for another query at that person's institution. The difference was the query that worked pulled the instance HRIDs from the public.inventory_instances table. We suggested that the person join the srs.marctab to the inventory_instances table to construct the where with the instance HRIDs from the inventory_instances table. The query worked with this change. We noted that there is some inconsistency in FOLIO and this is something to watch out for.
The zoom link for the meeting is https://umass-amherst.zoom.us/j/99254861410. Usual FOLIO password. Our lab sessions are open to everyone. Please bring your questions, examples, and comments about reporting and metadata.
ERM Working Group On going investigation on extracting ERM data with LDlite Started work on report of agreements by cancellation dates Investigated mermaid as tool for dta model documentation ERM Prototype and Query Development Status Bi-weekly schedule (next meeting 9th, November 9:00 AM ET)
RM Working Group subscription costs and subscription counts queries PR posted to folio-analytics exploring ways to make it easier to find options for reporting parameters in your LDP (e.g., a list of locations, item statuses, etc.) several queries for RM completed, but still need documentation, testing, and review for latest updates, see RM Prototype and Query Development Status
Reporting SIG Documentation Subgroup No changes Additional Context
External Statistics Working Group no updates currently new organizational/tracking scheme for JIRA, with pointers to queries in folio-analytics repository New organizational structure for External Statistics reports external statistics reports (e.g., ACRL) typically require running queries from different functional reporting areas these reports will be captured in JIRA under one UXPROD-XXXX report cluster issue, then the descriptions will point to each of the queries required to run them on the folio-analytics repository institutions will need to rank each of these 8 new UXPROD-XXXX report cluster issues each reporting development team will take responsibility for the queries in their area for the external statistics clusters
Product Council For all recent work on FOLIO Reporting SQL development: |
Advanced topic: querying non-Roman scripts | Stefan | content of database usually stored in unicode or UTF8 want to query, e.g., chinese symbols directly in query, can write them in the query if you are looking for whitespace in string, you can use hexadecimal or byte level representation can use functions to transform strings: encode, decode, convert_from sometimes something looks like whitespace but isn't, can't just tell by looking DBeaver has a hex view (or bytea?) can look in UTF-8 and unicode tables to find the expression for each symbol difficult to do this on byte level, easier at hexidecimal level because the tables of the expressions are easy to find on the internet if you have to save the query file, save as UTF-8 and not ASCII Documentation: Non latin symbols

Topics for Future Meetings | All | Follow-up on MARC status, Quickmarc/Data Import conflicts How to strengthen connections to SIGs and their developers to be kept in the loop about changes to the data model Show and tell how are institutions using the LDP examples of using the local schema Cornell's report ticketing system Rollout plans from institutions Ask someone on the sysadmin side to talk about LDP administration (Jason Root?) What is done in JIRA? (JIRA clean up)
Training topics adding test data in FOLIO snapshot How to do ad hoc querying with the derived tables How to use the LDP app using KNIME to build reports (LDP edition) use of local schema for custom tables more on MARC (ask Jennifer) using different applications (other than DBeaver) Insomnia for API queries? SQL LDP to metadb non-Roman script querying (Stefan) Metadb implications if schema changes, will that be relatively seamless? old fields still in history, but new fields in current? if fields are deprecated and removed, what happens if they come back again? how will deleted records show up?
GitHub Panorama LDLite (again?)
