@Bawolff I was re-reading our notes in light of the resumed interest in this project. Assuming we are not yet rolling out the sandbox approach per our discussion, I have began looking closely at the issues you raised:
@Xiaoyanghaitao if you want to target Vega 5.4.0 initially, you might as well put that version in the subject (or you could just say "latest production version")

Agree this would be great to have. I think this should be an API-level rather than an extension-level feature, because in many cases an extension would need to bridge the communication between inside and outside the frame. The system should allow:
- set up a separate initial configuration blob
- set up a separate resource loading for the iframe
- designate some resources as only available via the iframe loading (to restrict accidental loading by the primary site)
- establish a clear usage pattern for extensions to follow (this is more of a documentation than coding)
Do we want a separate ticket for Vega-Lite? Vega-Lite can be thought of as an "add-on" converter library that simply converts one JSON into a different JSON, without any other functionality (e.g. no XHR calls, no UI, etc). This way users can use a much simpler language VegaLite, and it will be dynamically converted to a full Vega.
@Bawolff is there anything in this ticket that is sensitive? There is a discussion about GSOC student tackling the Vega 3 upgrade, and they would need access to this discussion.
@Milimetric has any team at WMF decided to adapt it yet? From what I was told, there is already a GSOC student about to get started on this, and we could ask them to do some restructuring work as well. Which restructuring steps did you have in mind? BTW, it would be great if you could co-mentor this person as well.

A bot has been implemented and documented for this functionality. Needs a whole bunch of bot approvals, or a global bot flag. For now running it by hand for a few pages. Anyone interested in this functionality, we can now start building cross-site templates and lua modules...

@Milimetric I think the removal of Graphoid will be far more difficult than just keeping it. If you remove it, you will have to support multiple Vega versions on the client - not as trivial to do as it is for the Graphoid service (which was built with that support).
It's not about "allowing", it's just a matter of me (or someone else) to sit down and implement it :) Afterwards, I will have to document it in detail, and apply for a bot flag for my YurikBot (it has been dormant for a while now), preferably to be allowed on all wikis at once.

Another, not yet mentioned consideration: There was a significant syntax change between Vega 1.5, Vega 2, and 3+. Graph extension & Graphoid support both 1.5 and 2, but Graph ext does it in an imperfect way: browser only loads the latest version required, so if a page has both 1.5 and 2, it would just load 2. This only affects dynamic graphs (v2 only), but it really breaks during page preview -- only v2 graphs are previewed if both are present. When used as images from Graphoid, there are no issues (regular page viewing).
@mobrovac @dr0ptp4kt there is a much larger issue -- performance, and this is identical to maps: when a page loads, do you want to show a map / graph right away, e.g. if it is at the top, or do you want to load a large library, load all the data for it, and only then show the page? Or to show an empty box that eventually gets loaded? Live map requires leaflet, tile images, could get data from commons, could run sparql query (potentially overloading the server), etc. The exact same issues are for the graph - load Vega lib, load data, run sparql qeuries, etc. So if map needs it, graph needs it, and if servers can take both - sure. I would much rather have interactive content from the start.

@Anomie you are right that documentation does not say it will handle the entire ISO 8601, but I do think MW should handle at least a very common 2019-04-08T04:12:45+00:00-style format (only +00:00 / -00:00, not other timezones). It is, for better or worse, fairly common with Python, and supporting it shouldn't be a significant undertaking.

Here's a working implementation using the browser's prompt text box, based on the original idea by @Ricordisamoa. Copy it into your https://wiki.openstreetmap.org/wiki/User:___username___/common.js page. Note that the save will happen even if the user clicks Cancel because there is no good way to abort saving without crashing. This code can be directly used as a gadget.

This feature has been requested several times when adding Wikibase to OpenStreetMap wiki. I think the very first step we can already do is to make it possible for gadgets to add edit summary string during the "save" command. This way we can experiment with the UI implementation.

@A2093064 I think a much more intuitive behavior would be to use the "root" page, e.g. MediaWiki:talkpageheader as a fallback when a language-specific page does not exist, and use /en to override just English -- thus treating /en the same as any other language. Yes, it is possible to run a bot to generate all such pages, but ... ew :)
@A2093064 The talkpageheader message is set to a "-" by default - see code. This seems like a very strange behavior, especially because it makes this message useless for non-WP installations, or for any multi-lingual sites like Commons.

Note that Graphoid already supports POST approach (see v2 Graphoid api). You can post a graph spec to it, and it will return an image. But v2 was never actually used by any services, even though it is in production, just not exposed to end users. The issue with v2 is that we don't want to make MW parser (HTML rendering) dependent on an external service because of potential (unverified) speed concern - we need to generate some graph image URL without waiting for Graphoid to actually generate that image.

@Umherirrender that's an interesting idea, thx. It is not exactly the same because this wouldn't get me the redirect to redirect - e.g. A->B->C would only get me B->C without A->C.

@Pchelolo @Gehel I agree that Node 8 upgrade is urgent and must happen. This ticket was discussing Node 10, and mentioned that it was blocked on some dependencies, so I was proposing how to help with the difficulties of dependency upgrades, and k8s might be a good solution to that. I will be happy to chat on IRC. Thanks!!!
@Gehel is there a doc/procedure describing limits to docker deployment? E.g. would WMF have a docker repository and a well established build process that uploads to it, does it limit to the base images like "must use base Debian but not base Alpine", etc.
@MSantos and @Jhernandez , would it perhaps make things far simpler to migrate to use Kubernetes/Docker? Each maps service will be able to use any version of Node, or any native package, or even a different version/distribution of Linux as needed, and it will not affect any other services even if they are running on the same physical hardware. Even migration will be easier, because you will be able to use different version of Node on the same machine by different instances of Tilerator/Kartotherian.

Note that this is also possible with Sophox -- e.g. a SPARQL query can use Wikidata via federation together with all of OSM data itself (tags), plus attach the OSM geometry shapes to each wikidata ID it sees in the query result. Click "run query" under the example.

FYI, there has been a number of discussions at OSM on how to document disputed territories. See the latest proposal.

@akosiaris at the moment, yes, graphs are shown if they are in page-props db - i.e. generated from the last page revision. If you try to view an older version of the page, you will only see the graph image if it hasn't changed since then, otherwise you will see a broken image (because the hash would be different, and that hash would not be stored in the page props). On the other hand, you can view the older variant if you use page preview -- graphs will be rendered on the client, without using page props.

The actual data table is present. Was there any related code changes in MW?
I think the first step is to save HTML (preserve template/module parsing results). Next step - when snapshoting, switch to image permalinks. Lastly, implement "computed blobs storage" as this ticket describes, and also use permalinks when snapshoting.
These things don't need to happen at the same time. Even making it possible to view proper text of the older version of an article is a good first step.

Most of the time, Vega is used via a template, because otherwise you have a massive copy/paste of code without any benefit, while having no way to fix issues or improve appearance of all graphs en mass. Thus, per what @Anomie said - MCR is an orthogonal (in its current form) to the generated content. This actually has more similarities with the image thumb service than MCR (content is generated from "master" - wiki markup, and cached for usage by both the rendering service like Graphoid and directly from the client via the dynamic graph loading).

Are there any updates/progress on this issue? The OpenStreetMap Wikibase has both the local images and it supports Commons, which means every OSM Wikibase "image" property is actually two properties - one of "image" type, and another being a manually copy/pasted string of the local (OSM) wiki file - in case the file is not on Commons. It would greatly simplify things for OSM community if an image property would be a single "media", regardless of where it is actually stored. What could be done to solve this?

I agree with @Legoktm -- storing data blobs in page props was a hack. But to my knowledge, there is no good alternative storage for the parser-generated blobs. Essentially any system that needs independent access to those blobs would require something like this, essentially solving T119043
See related approach by Module:TNT -- it stores templatedata as a table (example). In this case <templatedata> will be dynamically generated during the parse time, and is available to every language/every wiki.

@akosiaris also, please add usage before the Varnish - to see how often graphoid objects are actually requested by the user, rather than how often there is a cache miss. Plus a similar stats for getting map snapshots.
However, that begs a question. If the caller of the graphoid service API already knows the hash of the graph, that means they either got it via talking to mediawiki, or that they calculated it themselves (aka they already have the entire graph). If they already have the entire graph, why not POST it to the service and obtain the resulting PNG themselves? Things become even more convoluted if the user is mediawiki itself (that's to my knowledge actually the case) at which case having mediawiki instruct another service to create requests back to it (the API endpoint actually) causes a cascading number of requests hitting the mediawiki API. Up to now this hasn't caused an outage, in my opinion simply because of the low traffic the graphoid receives.

I suspect the same issue is in Graphoid - it pulls the same bin data blobs via api

After some extensive work with Docker containers, it seems they are much cleaner, more portable, and much easier to deploy approach, without any performance or other issues. I would highly recommend repackaging under Docker.

@Lucas_Werkmeister_WMDE I think both should be fixed - it should never use unneeded parenthesis for single values, and when the VALUES list is short enough, it should be shown singleline. For a very long list, it should be shown like this:

IIRC, OSM can store polar regions just fine, but it is the OSM's own rendering that causes problems. Wikipedia does not use OSM's renderer, but it is similar in structure.
