Thank you, Mike and John.

Mike, as for the currency issue that you rightly raised, we plan to automate the creation of our PDFs with this nifty tool: https://github.com/hudmol/archivesspace_export_service It requires ArchivesSpace, but the basic pipeline could be added to any system of record: export EAD daily nightly for any updates, validate that EAD according to the schema, additionally validate it against further restrictions with Schematron, optionally create a PDF (heck, why not one that conforms to PDF/UA 😊), etc. Right now we're just using it to export the metadata, but once I've updated our PDF-production process, we plan to use this tool to keep our PDF up to date. I wish we could just generate those dynamically, upon request, but some of the files can be quite large.

John, you're right that PDF/UA is not a file format, but instead an ISO Standard. I've just been using Adobe Acrobat Pro so far to confirm conformance to that standard. Our current PDFs receive 20 warnings when using that tool. Our updated PDFs receive just 2 warnings, but both of those warnings simply mention that the "logical reading order" and the "contrast ratio" must be checked manually. Luckily, the reading order is just as sensible as any other finding aid, and the contrast ratio passes the standard's requirements since we're only using black text (or blue, for links) on a white background. So thanks to the power of the open-source community, for continuing to update and improve tools like Apache FOP, as well as the control we have over our pipeline with XSLT (I think/hope that means we won't need any manual intervention), I think that means we can achieve 100% conformance for all of our PDF finding aids. Other testing will need to be done, but I'm just happy right now to be passing the automated tests!

Also, I always appreciate hearing about your experience, John! I hadn't heard of the Deque Axe tool before, but I've just installed that alongside the Siteimprove Accessiblity Checker (https://siteimprove.com/company/press/2017/siteimprove-launches-free-google-chrome-accessibility-checker/). Thanks for the suggestion.

Mark

Hi Mark,



You've stepped into quite a sticky wicket. I can't offer specific advice, but maybe some helpful leads and my experience.



From my understanding PDF/UA is not a file format but a set of policy implementations, hence the difficulty 'validating' any specific instance. My experience with massive PDF authoring/508 remediation efforts suggest that no PDF authoring tool itself will get you 100% of what you need -- there is often some manual intervention needed. The easiest path to authoring a WCAG 2.0 (A, AA, or AAA) compliant PDF usually depends on the capacity of the source data/software, like using tooling available in MS Word to properly structure a document before PDF export, or a WCAG 2.0 compliant HTML document converted to PDF. The PDF validator link you offered seems to rely on a viewing software's capacity to render PDF/UA features rather than the technical aspects of a PDF file itself. We've been playing with VeraPDF's validators and I don't see PDF/UA listed as a target format. Acrobat XI Pro and Common Look are some other PDF-specific tools.



Unless someone is insisting on PDFA/UA as a deliverable, you might be better served focusing on the WCAG 2.0 piece especially focusing on the POUR concepts. The wiki site you mentioned in another listserve post states "The proposed rule identifies PDF/UA as equivalent to WCAG 2.0 for "appropriate content"." -- enough holes there to drive several trucks through. There is more validating technology and checklists for WCAG 2.0 compliance (which BTW is not the same as Section 508 accessibility) such as WAVE and Deque Axe. DHHS's new accessibility standard is WCAG 2.0 AA, although most public-facing websites mostly still refer to the old 508 checklists, so beware of the online content you consume!



FWIW, we are transitioning from an in-house tool to Deque Axe for HTML accessibility checking and issue management. Axe also has some developer integrations so you can run tests as you develop rather than remediate afterwards.



We're getting away from retrofitting/policing file formats to focusing on authoring/UX, so you are taking the path to righteousness.

This is a great discussion so far; thanks to everyone who has weighed in already!



To be clear: Personally, I'm a strong advocate for printable finding aids, but I don't think that archival repositories should be the ones printing them out (though I guess many do, like mine, during the editing / proofreading process anyway!) and/or filing them on site.



What's surprised me is that it seems like fewer and fewer finding-aid delivery services are offering PDFs or a similar option for download. ***I also can't find any examples of PDF/UA finding aids in the wild***. It is a relatively new standard, but it is also subject to Section 508, for example: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.section508.gov_blog_check-2Dpdf&d=DwIGaQ&c=cjytLXgP8ixuoHflwc-poQ&r=7Ez68qVcrmRD6nn1FqwoHBDEOxeRUCPm3xGvnFT0zjU&m=jQSdgB6bTJ1FBm3w47oowgJNH7Ui8xAAF9cb-r69_Hw&s=38yMvmjF3SYyrBVkaM-4cnHwxIM_w4grhBOnro-wvGk&e=



As for the technical aspects, Brian, I am relying on Apache FOP to create PDF/UA finding aids with XSL-FO (I thought about pursing a CSS option, but I don't know if any are viable right now to create PDF/UA documents). Apache FOP, which is open source, has been offering accessibility options since version 1.1, https://urldefense.proofpoint.com/v2/url?u=https-3A__xmlgraphics.apache.org_fop_1.1_accessibility.html&d=DwIGaQ&c=cjytLXgP8ixuoHflwc-poQ&r=7Ez68qVcrmRD6nn1FqwoHBDEOxeRUCPm3xGvnFT0zjU&m=jQSdgB6bTJ1FBm3w47oowgJNH7Ui8xAAF9cb-r69_Hw&s=6WzK-HX1w-7m6vtMhTh_Ibhf9XTqwzZ2V1NEf219F2k&e=, it looks like. I'm now using version 2.2, though, since it includes a number of fixes, and it also ensures that the document title of the finding aid is immediately recognized by Adobe Acrobat rather than the file name.



Anyhow, more in a few weeks once I have a few other concrete details worked out. But I'm still interested to hear more about this discussion in the meantime, especially if anyone else out there is working on creating PDF/UA finding aids. If so, let's talk ASAP. I've got a lot to learn still about this topic, so I'd love to share notes.

I did a lot of work on building PDFs via XSL-FO. They have the advantage of course, of being portable, but they can also provide good context — with breadcrumb running headers — and good navigation via the headers or the TOC. (Only useful if viewed on an electronic device of course, but it's complete and relatively compact.)



Unfortunately, Apache FO didn't seem up to the task and the proprietary FO engines we experimented with were very good but beyond our budget.

Not just because of the look of horror on researchers' faces if you were to take them away, but because archivists, too, need to understand whole collections wholistically sometimes. Especially for large collections with large finding aids, print is essential. PDF online or print eliminates confusing and distracting navigation, searching, filtering, and branding stuff that sits on a website. Then there's the problem of eyesight and projected light as opposed to reflected light....hurrah for print!

So far so good, but getting things set up was a bit more trouble than I expected, though that's probably because I knew essentially nothing about the PDF/UA standard before I started. Additionally, I have not been able to find any evidence of PDF/UA finding aids available online. Given that, I thought that I'd ask the EAS Section the following questions:

>

> • Can anyone point me to examples of PDF/UA finding aids?

> • Is anyone using any PDF alternatives to fill this gap? I've seen quite a few examples of print-friendly HTML finding aids, for example, but I'm not sure if any of those a) meet WCAG 2.0 guidelines and b) help researchers (since there are lots of ways to use an offline PDF, which I'm not sure that static HTML page would fulfill). At the same time, those print-friendly HTML files could easily be converted to other formats.

> • Last, and most importantly: are print finding aids a requirement at this time or not? I seem to remember some really compelling data from user studies (probably about 10 years old now) that would suggest that they are crucial for researchers.... And yet, I see fewer places offering PDF finding aids. There are a whole host of reasons for why this might be, but right now I'm just really curious what the list thinks about user needs in relation to print finding aids in 2018.
