scaling up Exhibit - an early experiment

2008-02-07 Thread David Huynh
Hi all, Some people have expressed a desire to use Exhibit on larger data sets, and I have mentioned that there is an effort to address that need. This is not a trivial engineering effort--it'll take months. But I'd like to show you a very, very early experiment (codenamed Backstage) to

David, can you elaborate on how this ties in with Longwell, if at all ? I ask coz I have played around with Longwell a bit (got the proxy thing kinda worked out in the end, by the way, non-trivial it was..) which was complicated to say the least! I got simple lenses working, but then got

The text is actually the text content, the url is, AFAICT, merely for doing rdf-ish things with converting scalar id strings to urls, so 'foo' becomes something like http://my.domain.tld/where/my/plot/is/index.html#foo. I never passed anything for filter, just did loadText(content,

Hi David, Although at the moment I cannot release my Artist/Artwork data publicly I hacked together some hierarchical data into an Exhibit (related to a student project here). As per usual it's hideously ugly but I thought it might be useful for example/testing services. The students may

David, This is great news! I too am interested in the relationship between backstage and longwell-csi. I presume you'll be suggesting migration paths from one to the other? do you intend for backstage to have the same kind of timeline support as is present in exhibit2.0 ? I will follow your

Yeah, you mentioned pivot tables earlier in the thread, but I haven't found a use for those yet. Which is odd, as I'm using everything else, right? ;-) Axel 2008/2/4, David Huynh [EMAIL PROTECTED]: Axel Hecht wrote: Hi David, yes, exactly, thanks for your help. I tried to find out

Re: Predicates or filters for exhibit collections

2008-02-07 Thread Axel Hecht
That worked, somewhat. The downside of this approach is that it still lists the full count of items that are in the original collection, so, in my case, I can't do a 32 of 47, as it reports some 32 of 59. To us, the we missed out on 15 is valuable information. I failed to create a filter

Re: (non) merging of data entries in exhibit table view

As David tought me, the id of an entry is derived from it's label. So if you want the two to be distinct, I guess you should create distinct id fields, while the labels can be ambiguous. Axel 2008/2/8, Yee-Ting Li [EMAIL PROTECTED]: Hi, if i have separate data 'rows' with the same 'label'

Please let me try to address all the questions that came up in one shot here. First, as I said, this is a very, very early experiment, so there are still many technical unknowns and few design decisions totally committed [waving hands] :-) I'm glad to see there's so much interest in this

How to embed non-Exhibit map markers in an Exhibit ?

JS newbie question: I want to add some Gmap markers to an Exhibit that are map constants, i.e. not handled by the faceted features, that won't be counted as an Item or made possible see or filter by facets. (E.g. a pin for Campus adm on a map of University institutes) I assume this is as easy to

Hi, i've been playing around with exhibit a bit more and i think i've found a bug in the formats. using my field (B) (defined from previous email), i thought i'd first try to just make sure that sorting on the numeric field works; so i set up the ex:columnFormats/ to be 'number'. however,
