pykde 允许对nepomuk的操作是十分有限的(实际上通过dbus的方式来走还要好些), 下面是一个用pykde 创建一个NEPOMUK资源的非常简单的例子.我在pykde的api中没有找到创建索引的相关的函数,以至于即便是有了对应的资源,可以在dolphin里面完全展示,但是通过nepomuk.query去搜索还是找不到资源信息.

如果有知道的朋友,希望分享一下.谢谢.

nepomuk资源创建和设置代码:

#!/usr/bin/env python2
# coding:utf8
# filename:nepomuk_test.py
# descption:a example for nepomuk


import sys
from PyQt4 import QtCore
from PyKDE4 import kdecore
from PyKDE4 import kdeui
from PyKDE4.nepomuk import Nepomuk


dummy_file = open('fummy.txt','w')
dummy_file.write('测试\n')
dummy_file.close()

result = Nepomuk.ResourceManager.instance().init() # create resoucemanager and connect to nepomuk resource database ,return 0 is ok,not is error.
if result != 0:
    sys.exit(result)

file_info = QtCore.QFileInfo("fummy.txt")
absolute_path = file_info.absoluteFilePath()
resource = Nepomuk.Resource(kdecore.KUrl(absolute_path)) # create or load a resource 

tagText = "tagtest"
tag = Nepomuk.Tag(tagText)
tag.setLabel(tagText)

resource.addTag(tag) # add tag
resource.setDescription("This is an example comment.") # set description
resource.setRating(4); # set rating

print "resource.exists() == ",resource.exists()
print "resource.isVaid() == ",resource.isValid()
print "resource.identifiers().length == ", len(resource.identifiers())
print "resource.type() == ",resource.type()
print "resource.types() == ",resource.types()
print "resource.resourceUri() == ",resource.resourceUri()
print "resource.resourceType () == ",resource.resourceType() 
print "resource.identifierUri() == ",resource.identifierUri()
