Licensing question

[ledifni]

I've read the LGPL license contract but I'm still a bit fuzzy on the responsibilities implied. I guess I should ask a lawyer about this but my questions are fairly simple, so maybe you guys can answer them.

1) Under the LGPL license, if I use the library in a website, am I required to display Isomorphic's logo on the page?

2) If I use the library as part of my own Javascript library, then use objects from that library in my website, I assume that the library I've created is open-source (i.e., anyone who wants it can have it). But is the website itself open-source? That is, if somebody wanted the entire website, including server-side code, would I be legally required to give it to them?

[Isomorphic]

1) No

2) This is a bit legally fuzzy because the boundary between an LGPL library and the application it is embedded in is a very technical issue and not easy to define cleary legally.

But Isomorphic's intent is that, no, your website does not become open source. Neither would an installable product embedding SmartClient LGPL become open source. The only thing that becomes open source are patches and enhancements to SmartClient.

Ok, thanks, that answers my questions. I have a further question, though: is it necessary to buy the commercial version to use the charting functionality?

[Isomorphic]

Yes, to use charting in particular, you do need a commercial license, an additional license from Isomorphic for the Analytics optional module, as well as a license from InfoSoft for FusionCharts. These are all relatively inexpensive, however, you could also embed free chart solutions in SmartClient as custom components if you can find one that works for you.
