Subject Re: migration from blojsom
Date Mon, 05 Nov 2007 15:41:52 GMT

I was thinking on creating a java tool that would connect to the blojsom database and insert
the data into the roller database. Unfortunately, I don't understand  (yet) what is the minimum
required data for the table "weblogentry" so that it will not break jRoller. My idea is to
migrate the entries only (without categories), disallow comments on those entries, but have
the correct posting date and time.

Unfortunately, there is no automated way to export from Blojsom and
import into Roller. There are a couple of ways you could do this work,
depending on you or your employees technical skill level.

1) Read the Blojsom data via JDBC then call the Roller API to import
it into Roller. I have some examples that show how to call the Roller
API via the Groovy scripting language.

2) Read the Blojsom data via MetaWeblog API, then use MetaWeblog API
to post it to Roller. Problems: 1) comments are not supported, 2) both
your Roller and Blojsom servers will have to be up and running at the

Does either of those approaches sound possible to you?
