In-Reply-To: [DCHAS-L] The DCHAS-L Archives are BACK and GOING PLACES! Part 2 of 2

Demystify: 
 I just dropped a huge organization update. EXCITING CHANGES. They are really powerful- see below. Using the numbering from my previous post:

0. The automation tests are in process and the list live list should be updating on a near-daily basis within the week.

1. The older posts are now formatted in the new format. One person has offered a mailbox that goes back to 2018, so that can fill the gap on preserving the original data. I may go back and extend threading to 2018 when I get that.

2., 3, 4, 6:  Each year now features FOUR INDICES  and STATS!!

i). Original: reverse chronological (newest first): https://www.ilpi.com/dchas/2025/ 

ii). Chronological (oldest first): https://www.ilpi.com/dchas/2025/index_chronological.html

iii). Threaded (for posts since mid 2022: https://www.ilpi.com/dchas/2025/index_threaded.html  And you can LINK to the conversation thread.

Threading that is confirmed through email headers is broken out, but for the pre-2022 posts or for modern posts where the threading information wasn’t reliable gives us another option - Subject-Based Groupings: https://www.ilpi.com/dchas/2025/index_threaded.html#subject-groupings  These are posts that probably belong together but we can’t guarantee it.

iv) Author Index - See every post by an author that year: https://www.ilpi.com/dchas/2025/index_authors.html And you can LINK to the author’s list.

v) Statistics - the Top 25 discussions for the year: https://www.ilpi.com/dchas/2025/statistics.html  Ideal for those who want the pulse of the list for research purposes.

Leaderboard - the statistics page tells you who has been posting the most for the year and you can jump to their posts in the author list.

All of these pages have improved highlighting/readability. On each, the current line lights up when you hover it so your eyes don’t glaze over when you confront a wall of text.


Threading and Subject Grouping go even further!

If you’re reading a post that is in a threaded conversation you can navigate it from within that the post. I went with this minimalist design to keep this readable on small screens and not clutter things up:

If the post is in a Subject-Based Group, there’s less certainty of a connection, so I went minimalist and simply linked it out to the Subject-Based Group to which it belongs:

And if the post you are reading is an “orphan” post with no known connectivity, you just see the regular ‘ole Previous/Next by Date navigation.

I still have a couple of under the hood changes to make, but what I’ve done is taken a resource originally meant to just preserve timeless wisdom (good and bad, true) as static pages is now becoming a full archival data system that can enable our Community to focus in on emerging trends, study the evolution of various safety topics/procedures, easily recall previously posted information, or simply read the posts without being confined to a mail program.

Questions and comments are welcome!

In Part 1 of my post I outlined the exciting new changes to the Archives. But even with all these changes there is still a lot to do, and possibilities are quite exciting - especially the last one listed here.

In approximate order:

0. Automating the processing of new posts in near-real time, and updating the site’s sitemap file + indexer rather than doing it in batches.

1. Convert the older posts to the new format and get them into the database. I have to write a program to do that, but I should be able to map most of it. If someone happens to have a virgin mailbox full of DCHAS posts prior to August of 2022, contact me off list, as that would be very very useful to the project and also provide a copy of the raw data prior to mid-2022 that I did not retain.

2. Once I have the older posts converted, I will be embarking on a project to enable threaded post viewing. So you can see a post and then, right below it, a list of all the responses sorted by date. The Previous and Next will work within the thread instead of unrelated chronological posts.

3. The user will be able to order the yearly indices by chronological or reverse chronological in either the current or threaded format.

4. The database format will also permit author indexes, subject indexes, attachment index etc.

5. With a little help from AI, I can probably come up with “Related Posts” we can add to pertinent posts.

6. The new database architecture will allow me to easily generate statistics reports or leaderboards so one can see at a glance what the most popular discussions have been or who has posted the most. I did this in my award presentation (https://acsdchas.wordpress.com/wp-content/uploads/2015/08/m3-toreki-12000-thoughts.pdf) but that involved a lot of manual manipulations. It would take about 1 second in the new architecture.

7. When I did the ILPI site revamp to have a universal navigation and sitewide search, I put in a powerful search tool: https://www.ilpi.com/dchas/2025/20251021.html
But down the road, I might consider leveraging the SQLite database that I've generated to add search features to the archives so one could search by specific author or organization etc. based on all that metadata. Or one could search only on particular subject lines etc.

8. All of this really moves me towards an ultimate goal I have discussed with a couple of folks off-list already.  And that's these recurring questions we see all the time on DCHAS-L. Well-plowed ground on stuff like floor drains, service animals in labs, satellite accumulation, employee v student etc.  There is a lot of good data there. And it's time to assemble that in one place.

So basically an FAQ, but much more than that. For select topics, we put forth an answer that isn't necessarily The Authoritative Answer, but more of a Community Consensus. Each summary would start with a succinct summary of the issue, a list of concerns/considerations, whether there is a consensus or how the answer depends on the particulars, pointing to the comments made in posts. Pros and cons, issues of concern etc. So, a one stop, easily maintained place where folks will find all the well-plowed ground sprouting a well-considered, thorough answer.

Now, in theory, that is the sort of thing that AI does easily these days. But AI gets stuff wrong. However, AI does do a great job of generating an initial summary if we tell it to start within only the DCHAS-L data set. That gives a jumping-off point that could be reviewed/created/updated by a DCHAS experts or small group. So the final summary answer we create would be RI (real intelligence). Each article would contain author information, links to authoritative/regulatory sources, and include a revision history. 

And once we create a summary I can put a link to the summary from each of the posts that led to the summary’s creation for good measure. So a robust resource. Assuming the data conversion project on the legacy posts proceeds smoothly, I think we could be able to try one of these out in the next couple weeks. I look forward to hearing YOUR thoughts on this.

Best wishes,

Rob Toreki
