NOTES

Purpose of establishing naming conventions:

organization should be simple, clear, and logical
need to be useful for end users
organization of reports, queries should be logical and simple as possible; library technology right now has incredible complexity, explodes in every corner; would like to organize things so it's clear and simple for people coming in
what we're really doing is taxonomy, which is both organization and naming

Example: Circulation Item Detail Report

there are two main types of circulation reports: aggregate counts, transaction details
"circulation" usually refers physical items, and usage usually refers to electronic

Elements relevant to naming:

Element	Value for Example Report	Description
Requirements ID	ID401
JIRA Ticket	REP-103
Name of Report	Circulation Transaction Detail Circulation Transactions Loans with Material Type Circulation Transactions with Bibliographic Detail Loans with Material Type and Bibliographic Detail Loans with Item Detail	The report itself is focused on how the report is going to be used, not about how to get the data. This will also be the name of the JIRA issue. Report Naming Construct by = filter or focus; appropriate for reports that aggregate transactions, not for transaction-level reports with = what the report includes, details only include as many extra clauses as is necessary to distinguish this report; if "bibliographic detail" is expected, don't need to list it Note: we should create a markdown file for each report that would live in a reports folder on GitHub; it should include original purpose of the report, description of the different queries, links to queries Can also link to report markdown files from the main ldp-analytics markdown file Question: how to keep track of work on things like this in JIRA
Name(s) of query(ies)	ex.: Count Loans for Locations	The query is how to get the data. Possible naming convention for short names: verb, source data, function example: count loans for locations or maybe noun, verb, function example: Loans - Count by Location with Material Type Will likely create JIRA issues for all queries, maybe in LDP project; then can link from LDP query issue to report(s) that contain(?) that query Idea from Angela: for noun, what is each row in the resulting table? is it a loan? a general circ transaction? a patron? for verb, either count or list? for modifiers, focus on with and by? only add ones that change between versions of queries?
Short name(s) of query(ies)	ex.: count_loans_locations	needs to be machine-readable, usable as a variable underscores are better than dashes because some programs don't like dashes in variable names may or may not need to look like the regular name; might need to be shorter use as GitHub folder name if adding something to indicate aggregation (_counts, _detail), add to end so you can sort like with short name, maybe use verb after nouns so things can be sorted by main topic of interest
Umbrella category for report	Circulation	Group reports by the 5 most used apps of FOLIO that reports will be generated for: users circulation (check out, check in, requests) inventory finance and orders resource management just use umbrella category to organize reports, not to name them (could be the directory structure in LDP GitHub) use tagging (e.g., in GitHub?) to help organize reports, maybe to add original functional area to query
Additional information that would be useful when browsing reports in, e.g., GitHub: date of query tag indicating original functional area

Report Name Discussion:

Question: do we really need to specific "bibliographic detail" in the report name? Is it reasonable to assume bibliographic data will be included?

when is something like that assumed to be in a report, and when does it need to be called out in the name?
can we just make a general "Loans" report with all of the columns and let people discard columns they don't need later?
- end users would probably be happier with more specific subset reports already created for them; they will want to see both "Loans with Material Type" and "Loans with Service Point", even if at their core they are similar and we could hypothetically create a master "Loans" query with all necessary columns
- going forward, maybe that's how we organize our work on report clusters: create master queries will a large set of columns needed across several reports, then develop queries that build off that query to tailor the results for specific report requests (see workflow below)

Upper-level grouping options:

Circulation (use App names/API structure; users, circulation, inventory, finance and orders, resource management)
- maybe this is most readable for non-expert analysts
Resource Access (stick with current functional areas)
- useful for report development, but maybe not useful for UX; could potentially just include tags on GitHub

General workflow for reports:

cluster reports by topic/purpose/common data elements
figure out the query that includes all necessary data elements (full, larger report with all the difficult joins)
build additional queries that filter/subset that full query as specified

Filtering Questions and Names of Reports and Queries

only include columns for which there is a one to one join
Where vs Select Filtering
- Query = join loans
- Query = filter material types

Linking between JIRA and future report documentation (GitHub):

Issue title should change to the new naming convention
don't try to create new JIRA projects for the umbrella categories; all dwreport issues stay in REP
to filter down to reporting umbrella categories, could create a new field or just add more tags. Solution TBD.

Special cases:

external reports (e.g., ARL) - the "report" will be a collected set of queries required for external statistics; each of the queries, however, might be useful for other reports
- Question: how does that work with GitHub? If we update the query in one place, do we just have to remember to update it everywhere else it might be used?

Resource Access Visit

Topics

how can reporting step in for workflow, which won't cover everything RA needs in first iteration
- example: items that need to change state after certain amount of time
- RA will need to sit down and identify things that it was assumed the workflow engine would take care of
- is any of it reporting functionality? may be, but some may just be normal reports
- maybe set up a meeting with RA SIG, small group?
- RA will probably just work on it together first
- this may be part of a great use case for additional development resources
- will have to do some analysis of in-app vs. LDP; only have resources to work on LDP (check out the new LDP vs. In-App explanation)
In-App vs. Data Warehouse
- changing UXPROD-933 to REP, is a partial duplicate of UXPROD-1327, so no need for two in-app reports and makes sense to be able to run this kind of report against historical data
- for data privacy, reports with patron identifiable data may need to stay in-app; includes things like fees/fines?

building report prototypes is like a mycelial network: you build one report, but then can tailor different branches

Demo of schemaspy, GitHub, test data

Resource Access has additional report requirements

App Interaction: ERM + eUsage + Reporting

The eUsage app would like to include a statistics summary that would require joining data between ERM and eUsage modules. Rather than having the app know how to join its data to another app, should they try to leverage the joins that the LDP is already doing? How might that work?

maybe app would connect to LDP through ODBC and submit query? or maybe we would offer an LDP API?
problem: they would have to be okay with day-old data, wouldn't be able to harvest COUNTER data and immediately see cost/use
- this does seem like a concern, people might want pretty fast responses, especially if they're using this stats summary to perform QA on the data they just uploaded
  - (Q: could they do QA on the COUNTER data separate in the app, before it gets joined to cost data?)
- don't forget, day-old is just for go-live, may eventually be faster
this should really be a conversation across apps:
- other apps might (will) need to join data, too
- if other apps are joining data directly and don't need the LDP, maybe we shouldn't do something special for ERM; but maybe everyone will want to run from the LDP

Note: this meeting also included a tangential but important discussion about non-COUNTER data in the eUsage app. There are many difficulties getting non-COUNTER data to be usable in the app - it could be uploaded, but any calculations are hard to do unless you have the known structure of something like COUNTER. Talked about possibly adding a special uploader to match non-COUNTER data to important fields, but even that might be out of scope. Is there a chance the LDP would be a better option? If the LDP allows for custom data (could be a separate, local data table), then they could at least query against COUNTER and non-COUNTER data using the same database. That might not be perfect for the analysts, though, who would prefer to be able to quickly upload data in whatever format they have (JSON?) and be able to calculate cost/use easily.

Planning for Closing Session

We have 10 minutes to summarize what we've done
Angela will talk about naming conventions
Sharon will talk about RA
Scott will talk about ERM, RM
Should we cover eUsage? Reviewed the discussion yesterday, think it's possible to repurpose the LDP joins for cross-App issues, but not sure if we'll be offering anything custom

Action items

add a user story to the JIRA issue about storing effective location in loan (UXPROD-1432)
