Most of what I know comes from this:
http://lucasmanual.com/mywiki/OpenOffice
Other points
1. You can start LibreOffice from a script, but you can't connect to it in
that same script. That one cost me half a day.
2. LibreOffice is gonna crash. You'll need a cron job to check if
LibreOffice is still running and restart it if it's died.
3. It's slow. If LibreOffice is going to do much work, use the scheduler
as Wilkus suggests.
4. Get a version of Python with uno baked in.
5. ZipFile can unpack an odt document. Beware on upload, though; don't
mess with the odt doc until after it is saved.

Here's the code I use to start LibreOffice:
#! /usr/bin/python2.7
import uno, subprocess, shlex, pyuno, os, socket ## prune this import list!
# fire up libreoffice
rgs = '/usr/lib/libreoffice/program/swriter
-accept="socket,host=localhost,port=2002;urp;StarOffice.ServiceManager"
-norestore -nofirstwizard -nologo -headless'
args = shlex.split(rgs)
lo = subprocess.Popen(args)
++++++++++++++++++++++++++++++++++++++++++++++++++++
Here's a controller.
def do_documents(form):
import uno, os, socket, string ## prune this list
from com.sun.star.beans import PropertyValue
try:
os.mkdir(request.folder + 'temp_pdf')
except OSError:
pass
package_name = db.document_packages[request.args(0)].name
items = {}
# processing a hand made form
# get the doc id, make a list of fields for each
for k,v in form.vars.iteritems():
k_split = k.split('_')
if len(k_split) < 2 or k_split[0][:3] != 'id=':
continue
doc_id = k_split[0][3:]
if doc_id not in items:
items[doc_id] = []
items[doc_id].append((k_split[1], v))
# now attach the the running LibreOffice instance
# still need to implement a check if running and recovery if not
local = uno.getComponentContext()
resolver =
local.ServiceManager.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver",
local)
context =
resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
desktop =
context.ServiceManager.createInstanceWithContext("com.sun.star.frame.Desktop",
context)
for k, v in items.iteritems():
rcrd = db.document_templates[k]
path = request.folder + 'uploads/' + rcrd.body
tmplt = desktop.loadComponentFromURL("file:///"+path ,"_blank", 0,
())
print type(tmplt) # diagnostic
search = tmplt.createSearchDescriptor()
for val in v:
search.SearchString = '{{='+val[0]+'}}'
found = tmplt.findFirst(search)
while found:
found.String = string.replace(found.String,
unicode('{{='+val[0]+'}}', 'utf-8'), unicode(val[1], 'utf-8'))
found = tmplt.findNext(found.End, search)
## next step is to implement the pdf conversion. I THINK this code will do
it
## property = (PropertyValue("FilterName" , 0, "writer_pdf_Export" ,
0 ),)
## newpath = request.folder + 'temp_pdf/' + os.path.split(path)[1]
## tmplt.storeToURL("file:///" + newpath,property)
## tmplt.dispose()
tmplt.storeAsURL("file:///home/cjk/wtf.odt",()) # not final code
tmplt.dispose()
