[Opensim-dev] A Online HyperGrid Link list for OpenSim's 2ndbirthday

Fri Jan 16 18:02:45 UTC 2009

Okay well I have done some more work on the code side, and tried to detail it in a bit more detail on http://opensimulator.org/wiki/Hypergrid#Hypergrid_Lists

that is just a first draft attempt, so if anyone understands what I mean and wants to clean that up a bit, feel free.

Anyway so I think from the code side, the basic support needed is there now.
Its just getting the website for hosting such a list up. I think I might have found someone who is interested in doing that. But nothing certain yet.

I might take on this, except that I have another trip coming up, and I'd rather spend my OpenSim-time until then making sure that TPs are rock solid; so I don't think I'll have time to do this.

 The next best thing is this list:
 http://opensimulator.org/wiki/Hypergrid#Public_Hypergrid_Nodes

 People can add their node info there; and everyone else can add that info to their startup_commands or whatever other link-region means they use.

 In the UCI Grid, for example, I already have several of those nodes on the Map; I will add all of them as they show up on that list. And i'll also add any others that are not there but that show up on this other list:
 http://opensimulator.org/wiki/Second_Birthday

 So, unless someone pulls something automated soon, plan B is to do it manually.

 I was hoping that someone in the community would make a simple website and host it. 

 I guess if no one else takes it up, then I'll have to see.

     Yours will be perfect, please drop the info so we can place a teleporter - web link for our guests to your show n tell for Hypergrid. Thanks MW

 I think this is a great idea, but the questions that come to mind, are: how is the mapping handled for these sub lists and how does a user say that they don't want these sub lists on their map. I think the number of options required could be quite high and think its something that needs some thought before any attempt to add these functions is made.

That way a larger grid could configure itself and individual regions could join in without requiring an update to a central web site.

         I've just added some very initial support for reading Hypergrid link data from xml files, that includes support for the xml files being on a webserver.

 The xml file has a format like:

<Nini>

 <Section Name="Region1"> 
   <Key Name="xloc" Value="1002"/>
   <Key Name="yloc" Value="1006" />
   <Key Name="externalPort" Value="9006" />

   <Key Name="externalHostName" Value="osl2.nac.uci.edu" />
   <Key Name="localName" Value="OSGrid-Gateway" />

 </Section>
 <Section Name="Region2"> 
   ...
 </Section>

 ...
</Nini>

 And to make a region load it and create the links, you use the console command:  link-region <URI> [<excludeList>]

 The excludeList parameter is so that certain links in those xml files are ignored.

 With the format: excludeList<xml SectionName>[;<xml SectionName>]. 

 The main thinking for this is so that a single list for a certain group/event could be created. Then everyone interested in it, just adds their own region data to the list. 

 But so they can also point their own region at that list, they just add the section name they used to the exclude list, so that it doesn't try to link to itself.

 If we can find a way of having a xml file on a webserver that people can add new entries to (maybe through a form script). Then I think it would be a good idea to have such a list for OpenSim's 2nd birthday.

 Although this idea really needs some sort of automapping or at least better configuration of the map locations that the regions are placed at. 

 I think if everyone just agrees that a certain area on the map [so say x,y - x+25, y+25] is reserved for link regions, that it is workable for now.
