Why do not all (free / open source / LGPL) addons have install/download buttons on the marketplace?

[mathias_lin]

I noticed that some addons don't have install/download buttons on their marketplace page, and some do. For example, the multi-tenant does not have a download button, the JSF UI addon has a button. The download button seems to be not available for addons that "require registration".

However, I don't understand the logic, benefit or added value here. If you can download the i.e. multi-tenant addons from a registered Nuxeo instance and get the zip from there and deploy it to an unregistered instance, or build it from the github repo and deploy it to an unregistered Nuxeo instance, what's the point of not offering a download button on the marketplace in the first place, or what is the idea behind the registration here for such addons?

It make sense that commercial addons would not have a download button (obviously), but why do some free (=LGPL, not paid) addons not have it either? And why would a registration (not subscription) be necessary for the multi-tenant module for example, if it's free (=LGPL, not paid) anyway?

Another question that I have is in this regard: does the requirement for an addon for a "registered account" mean the same as "suscription required", or is the account registration and using it after the trial still free?

Florent Guillaume: "Nuxeo LTS (Long Term Support) hotfixes via Nuxeo Connect is a service we provide that gives registered users very simple updates to the latest hotfix version of Nuxeo. That takes time and resources on our part. We don't think that registering through Nuxeo Connect to get this service is that much of a hurdle (it's free)."

There are three levels of package availability: public, restricted, private. The private level is for packages with very limited ownership and visibility (specific customer, Nuxeo internal, etc.) The restricted level is for packages requiring a "registered account", which means the same as a "paid subscription" or a "trial".

You are confusing free and open: an addon can be open source (ie freely installable by hand) while its package not being freely downloadable (ie the additional service provided by Nuxeo). The quoted sentence from Florent Guillaume is still valid. Wether a package is public or restricted depends on the commercial strategy, the addon importance (JSF UI is public because required in many cases), the related technology (is it itself free or not), etc.

Using a registered instance to download a package, then installing that package on an unregistered instance (ie bypass the system rules) is not fair and I highly discourage such a practice: at one time, you will get in troubles. Being it with updates, hotfixes and legal issues.

Building by hand is fair and perfectly acceptable. When doing so, you know that you are in the rails, only not getting benefits from a paying service.

Is it correct that in order to just get hotfixes for the multi-tenant addon (assume that's the only additional addon the client needs), and if the client would not need any other restricted/commercial addon or technical service, it would cost 47,000 EUR / year, or what would be the cost?(http

I'm not the right person to explain those considerations in details but yes, it's all about a balance between the cost of DIY and the subscription fees. Nuxeo offers its services as whole packages including hotfixes, Studio, consulting, support, etc. There are various degrees but no small offer focused on a unique addon.

Ok, thanks for the info.

Note that in the quoted message from me, I specifically talk about hotfixes. Pre-packaged hotfixed that are easily applied are provided exclusively through the Nuxeo Online Services subscription for Nuxeo customers.

People are of course always free to download and compile the code themselves.

Ok, thanks for clarification! (Not clear about the download button though. Obviously manual installation does not provide hotfixes, but this goes for JSF UI addon as well as for the multi-tenant addon. If it's not recommended to do this for the multi-tenant addon, it should also not be recommended for the JSF UI addon.)
