The talk is not about pdf viewers but about framework/APIs that developers can use to build all those 'others' solutions. pdfjs.express makes this a piece of cake, you get the source, and companies can outdo competition will less developer $$$ sunk into reinventing the wheel

Actually it's NOT, you're quote "working on it". Stop spreading misinformation. Right now it's 100% commercially licensed in a public repo. Not open source in any way, shape, or form.

I don't think this solution is doing what you are looking for. To detect tables reliably in PDF you need some heavy-duty AI like https://www.pdftron.com/pdf-tools/pdf-table-extraction/

Yeah but this isn't open source. It's proprietary with source available, despite what you claim in numerous places throughout this thread. You're building a proprietary product on top of an open source project. You also chose a name that creates the impression that you built the original open source project, which you don't appear to be contributing anything back to. Comparing yourselves to Red Hat has to be a joke, right?

No, Express will be available under dual AGPL/commercial license.

Says the employee of the company behind it!

Their website and marketing of this fact (is it a fact?) is very confusing or misleading. The comparison at https://pdfjs.express/pdfjs-vs-express says "PDF.js is an open-source PDF library that was created by Mozilla in 2011 to let you open and render PDFs in web browsers using JavaScript. PDF.js Express is a fully-featured commercial PDF.js viewer with a modern and customizable UI."

I would really like to know whether or not "PDF.js Express" is open source. Why? Because I've done a lot of work on react + pdf.js already (for a latex editor), and it's been high on my todo list to add annotation features. So PDF.js express significantly overlaps with something I'm very seriously planning to do...

Evidently I should clarify that by "open source", I mean "released under an OSI approved license" (https://opensource.org/licenses). Maybe robocop2018 means "open source" in the sense of "there is possibly minified non-human readable source code that you can look at under a very restrictive non-OSI license"?

PDF.js Express is not open source.

It is available under dual AGPL/commercial license so indeed it's open source by any definition. We'll clarify this on the site. Thanks for feedback

The license reads "WebViewer React UI project/codebase or any derived works is only permitted in solutions with an active commercial PDFTron WebViewer license. For exact licensing terms please refer to your commercial WebViewer license. For use in other scenario, please contact sales@pdftron.com".

That is a proprietary source-available license, very much not open source at all.

Please don't use the term open source, not even in quotes, if your code is not available under a license that meets the Open Source Definition or the Free Software Definition.

So which is it? robocop2018 is claiming it's AGPL/commercial dual-licensed, but you say it just has the custom license and that's the only license in the repo?

We are in the process of updating the site. The product will be licensed under dual GPL/commercial terms (re: what it means see bit.ly/2JD0Yj0)

What license is this under? Where can I get the source code?

The website says it is open source in one place, and then in other places it says it is a "commercial PDF web viewer that wraps around the PDF.js open-source rendering engine."

I didn't see any link to the source code or license anywhere on the site?

See other messages. The code is available and will be licensed under dual commercial/AGPL terms (similar to bit.ly/2JD0Yj0)

Are you affiliated with PDFTron, the company that created this? Your posting history suggests you are. Please disclose if so.

Yes, I am employed by PDFTron. I've been leading this project since early 2019.

I was asking "robocop2018". Are you him?

I am not "him" :) though I work at PDFTron

As Nick says the project is open source (https://github.com/PDFTron/webviewer-ui).

Express is available under under dual AGPL/commercial license ( similar to iText and lot's of other popular OSS )

There is no mention of AGPL anywhere in that repository. There is just a LICENSE file with a completely different proprietary license: it is not open source at present. If you intend to make it open source, you need to change the license to an open source one.

Where is the AGPL license?

It's https://opensource.org/licenses/AGPL-3.0 Or summary of what it means bit.ly/2JD0Yj0

If you are talking about info on the site & git, we are working on it. There will be many changes over next few weeks. Stay tuned :)

Yes, I'm familiar with the license.

The question was about your claim that it was already licensed under it. Apparently it's not, but you're "working on it". Umm, okay.

The parent didn't ask if it was a fork or not.

The point being that this is an extension, and contributing back to that dependency is orthogonal.

If they contribute back was the question.

No doubt, WebAssembly has lot's of going for it. I think the purpose of the article was to bring awareness around current performance and memory limitations so that WebAssembly can live to its full promise. Not so much an argument to keep PNaCl around.

mpweiher, you are correct! PSPDF is a pdfium lipstick. You can find its license in binary sdk-s or simply ask them. Included or derived work must be disclosed!

Also using the pdfium via Enscripten is not news (https://github.com/coolwanglu/PDFium.js is 3 years old).

On commercial, battle tested side PDFTron offers PDFNetJS & WebViewer for years https://blog.pdftron.com/2015/11/10/pdfnetjs-html5-pdf-viewe... (http://xodo.com/app is the demo referenced in the presentation).
