[SOLVED] gexf4j and spells

Post by redcrow » 13 Apr 2012 17:21

Hi everybody,

I'm working on a parser to transform a file from "log-style" to a GEXF graph. Then I'd like to import that graph into Gephi 0.8. In order to build the GEXF file I'm using the gexf4j library. Unfortunately I've noticed that there's nothing for the "spell" attribute. I've just found a "Slice" class, but the history of Gephi (http://gexf.net/format/history.html) says that slice are renamed to spell... so, I want to be consistent with the last version of Gephi.

What should I use?

Thank you for your help.

Regards,
Francesco

Hi,

You need to use "spells". Unfortunately, gexf4j seems not maintained anymore, and may not be compliant with the latest changes of the GEXF format.

Hi,

since yesterday I've worked on gexf4j source to change it in according to latest version of GEXF draft, that is 1.2 (Gephi 0.8 compatible).

I'll let you know when I finish the changes.

Regards,
Francesco

Hi,

I've almost completed the changes, but I have to implement timeformat in DOUBLE and INTEGER form (date and dateTime are done).
I haven't found anything on GEXF schema... What's their official form? E.g., 2012 for integer and 2012.04 for double?

Thanks,
Francesco

Ok, so the integer part is the year, while the decimal part is the month.

Good, thanks.

Ok, I've finished these changes:

- "timetype" attribute is renamed to "timeformat".
- <slices> and "slice" are renamed <spells> and "spell" correspondingly.
- Now the "timeformat" can be integer, double (default), date, dateTime
- Open intervals (non-inclusive) are added: "startopen" and "endopen" attributes.
- Bug fix on all "Attribute setTitle(String title)": the expression in checkArgument was wrong.

Now, how do we organize the update?

Bye,
Francesco Ficarola

No I mean, time can be encoded as an integer, like when you have snapshots. It could also be any floating point number.

Ah ok, so it can be any number, like a "user-timestamp". I'll fix that.
