21 <title>Automatic Recording for KiSS Hard Disk Recorders</title>
25 KiSS makes regular updates to their site that sometimes require adaptations
26 to the crawler. If it stops working, check out the most recent version here.

29 <title>Changelog</title>
32 <title>7 September 2006</title>
34 <li>KiSS modified the login procedure. It is now working again.</li>
35 <li>Generalized the startup scripts. They should now be insensitive to the specific libraries used. </li>
39 <title>31 August 2006</title>
41 <li>Added windows bat file for running the crawler under windows.
42 Very add-hoc, will be generalized. </li>
46 <title>24 August 2006</title>
48 <li>The crawler now uses desktop login for crawling. Also, it is much more efficient since
49 it no longer needs to crawl the individual programs. This is because the channel page
50 includes descriptions of programs in javascript popups which can be used by the crawler.
51 The result is a significant reduction of the load on the KiSS EPG site. Also, the delay
52 between requests has been increased to further reduce load on the KiSS EPG site. </li>
54 The crawler now crawls programs for tomorrow instead of for today.
57 The web based crawler is configured to run only between 7pm and 12pm. It used to run at
64 <title>13-20 August 2006</title>
66 There were several changes to the login procedure, requiring modifications to the crawler.
69 <li>The crawler now uses the 'Referer' header field correctly at login.</li>
70 <li>KiSS now uses hidden form fields in their login process which are now also handled correctly by the
75 <section id="overview">
76 <title>Overview</title>
79 In 2005, <a href="site:links/kiss">KiSS</a> introduced the ability
80 to schedule recordings on KiSS hard disk recorder (such as the
81 DP-558) through a web site on the internet. When a new recording is
82 scheduled through the web site, the KiSS recorder finds out about
83 this new recording by polling a server on the internet.
84 This is a really cool feature since it basically allows programming
85 the recorder when away from home.
88 After using this feature for some time now, I started noticing regular
89 patterns. Often you are looking for the same programs and for certain
90 types of programs. So, wouldn't it be nice to have a program
91 do this work for you and automatically record programs and notify you
92 of possibly interesting ones?
95 This is where the KiSS crawler comes in. This is a simple crawler which
96 logs on to the KiSS electronic programme guide web site and gets
97 programme information from there. Then based on that it automatically
98 records programs for you or sends notifications about interesting ones.
101 In its current version, the crawler can be used in two ways:
104 <li><strong>standalone program</strong>: A standalone program run as a scheduled task.</li>
105 <li><strong>web application</strong>: A web application running on a java
106 application server. With this type of use, the crawler also features an automatic retry
107 mechanism in case of failures, as well as a simple web interface. </li>
112 <title>Downloading</title>
115 At this moment, no formal releases have been made and only the latest
116 version can be downloaded.
119 The easy way to start is the
120 <a href="installs/crawler/target/wamblee-crawler-0.2-SNAPSHOT-kissbin.zip">standalone program binary version</a>
121 or using the <a href="installs/crawler/kissweb/target/wamblee-crawler-kissweb.war">web
125 The latest source can be obtained from subversion with the
126 URL <code>https://wamblee.org/svn/public/utils</code>. The subversion
127 repository allows read-only access to anyone.
130 The application was developed and tested on SuSE linux 9.1 with JBoss 4.0.2 application
131 server (only required for the web application). It requires at least a Java Virtual Machine
132 1.5 or greater to run.
137 <title>Configuring the crawler</title>
140 The crawler comes with three configuration files:
143 <li><code>crawler.xml</code>: basic crawler configuration
144 tailored to the KiSS electronic programme guide.</li>
145 <li><code>programs.xml</code>: containing a description of which
146 programs must be recorded and which programs are interesting.</li>
147 <li><code>org.wamblee.crawler.properties</code>: Containing a configuration </li>
150 For the standalone program, all configuration files are in the <code>conf</code> directory.
151 For the web application, the properties files is located in the <code>WEB-INF/classes</code>
152 directory of the web application, and <code>crawler.xml</code> and <code>programs.xml</code>
153 are located outside of the web application at a location configured in the properties file.
158 <title>Crawler configuration <code>crawler.xml</code></title>
161 First of all, copy the <code>config.xml.example</code> file
162 to <code>config.xml</code>. After that, edit the first entry of
163 that file and replace <code>user</code> and <code>passwd</code>
164 with your personal user id and password for the KiSS Electronic
170 <title>Program configuration</title>
172 Interesting TV shows are described using <code>program</code>
173 elements. Each <code>program</code> element contains
174 one or more <code>match</code> elements that describe
175 a condition that the interesting program must match.
178 Matching can be done on the following properties of a program:
181 <tr><th>Field name</th>
182 <th>Description</th></tr>
185 <td>Program name</td>
189 <td>Program description</td>
193 <td>Channel name</td>
197 <td>Keywords/classification of the program.</td>
201 The field to match is specified using the <code>field</code>
202 attribute of the <code>match</code> element. If no field name
203 is specified then the program name is matched. Matching is done
204 by converting the field value to lowercase and then doing a
205 perl-like regular expression match of the provided value. As a
206 result, the content of the match element should be specified in
207 lower case otherwise the pattern will never match.
208 If multiple <code>match</code> elements are specified for a
209 given <code>program</code> element, then all matches must
210 apply for a program to be interesting.
218 <th>Example of matching field values</th>
221 <td>the.*x.*files</td>
222 <td>"The X files", "The X-Files: the making of"</td>
226 <td>"Star Trek Voyager", "Star Trek: The next generation"</td>
231 It is possible that different programs cannot be recorded
232 since they overlap. To deal with such conflicts, it is possible
233 to specify a priority using the <code>priority</code> element.
234 Higher values of the priority value mean a higher priority.
235 If two programs have the same priority, then it is (more or less)
236 unspecified which of the two will be recorded, but it will at least
237 record one program. If no priority is specified, then the
242 Since it is not always desirable to try to record every
243 program that matches the criteria, it is also possible to
244 generate notifications for interesting programs only without
245 recording them. This is done by specifying the
246 <code>action</code> alement with the content <code>notify</code>.
247 By default, the <code>action</code> is <code>record</code>.
248 To make the mail reports more readable it is possible to
249 also assign a category to a program for grouping interesting
250 programs. This can be done using the <code>category</code>
251 element. Note that if the <code>action</code> is
252 <code>notify</code>. then the <code>priority</code> element
259 <title>Notification configuration</title>
261 Edit the configuration file <code>org.wamblee.crawler.properties</code>.
262 The properties file is self-explanatory.
271 <title>Installing and running the crawler</title>
274 <title>Standalone application</title>
276 In the binary distribution, execute the
277 <code>run</code> script for your operating system
278 (<code>run.bat</code> for windows, and
279 <code>run.sh</code> for unix).
284 <title>Web application</title>
286 After deploying the web application, navigate to the
287 application in your browser (e.g.
288 <code>http://localhost:8080/wamblee-crawler-kissweb</code>).
289 The screen should show an overview of the last time it ran (if
290 it ran before) as well as a button to run the crawler immediately.
291 Also, the result of the last run can be viewed.
292 The crawler will run automatically every morning at 5 AM local time,
293 and will retry at 1 hour intervals in case of failure to retrieve
294 programme information.
299 <title>Source distribution</title>
301 With the source code, build everything with
302 <code>ant dist-lite</code>, then locate the binary
303 distribution in <code>lib/wamblee/crawler/kiss/kiss-crawler-bin.zip</code>.
304 Then proceed as for the binary distribution.
309 <title>General usage</title>
311 When the crawler runs, it
312 retrieves the programs for tomorrow. As a result, it is advisable
313 to run the program at an early point of the day as a scheduled
314 task (e.g. cron on unix). For the web application this is
315 preconfigured at 5AM.
318 If you deploy the web application today, it will run automatically
319 on the next (!) day. This even holds if you deploy the application
320 before the normal scheduled time.
324 Modifying the program to allow it to investigate tomorrow's
325 programs instead is easy as well but not yet implemented.

333 <title>Examples</title>
336 The best example is in the distribution itself. It is my personal
337 <code>programs.xml</code> file.
