3Data Export
4***********

6Regular data exporters (1) collect objects from specific containers,
7(2) iterate over the collected objects, (3) extract and mangle
8information from each object, (4) write the information of each object
9into a row of a CSV file and (5) finally provide the file for
10download. The CSV file is neither stored in the database nor archived
11in the filesystem. (3) and (4) means a flattening of the hierarchical
12data structure, i.e. a mapping of objects to flat relational data to
13be stored in a CSV table. The extracted information must not
14necessarily be based only on static attributes of the collected
15object. The data, finally stored in the CSV file, can also be derived
16from parent or child objects, or dynamically computed by the object's
17methods and property attributes. These methods and properties can
18retrieve information from everywhere in the portal's database. In the
19following we list all exporter classes including two attributes and a
20method description. The `fields` attribute contain the column titles
21of the export file. These are not necessarily only attributes of the
22exported objects.
23
24.. note::
25
26  The list of exported columns usually underlies heavy customizations.
27  In the Kofa base package only very few columns are being exported. In
28  some Kofa custom packages tons of data are being gathered from
29  applicants and students and the number of columns increases
30  accordingly.
31
32The `title` attribute unveils the name of the exporter under which
33this exporter will be displayed in the user interface. The
34`mangle_value()` method shows how some of fields are being dynamically
35computed.

147Student Data Exporters
148======================
149
150When starting a Student Data Exporter in the Data Center all student
151records will be taken into consideration, no matter what or where a
152student is studying. The exporter can also be started 'locally' at
153various levels in the academic section. Starting one of the exporters
154e.g. at faculty or department level means that only the data of
155students are exported who study in this faculty or department
156respectively. The exporter can also be started at certificate level.
157Then only the data of students, who are studying the named study
158course, will be taken into account. At course level the data of those
159students are being exported who have attended or taken this specific
160course.
161
162Student Data Exporter can be further configured through a
163configuration page. Search parameters like the student's current level,
164current session and current study mode can be set to filter sets of
165students in order to decrease the size of the export file. The set of
166filter parameters varies and depends on the 'locatation' from where
167the exporter is called. A completely different set of filter
168parameters is provided for courses. In this case the session and level
169can be selected when the course was taken by the student.

233
234  The above exporters refer to a specific content type (object class).
235  They export all attributes of these objects and a few additional
236  parameters derived from the parent objects. These exporters can be
237  used for reimport, or more precisely for backing up and restoring
238  data. The following 'special' exporters are made on request of some
239  universities to collect and compose student data for analysis and
240  postprocessing by the university.
