Hello,
Currently the xml metadata are stored in the same directory with indexes.
The collection information was also stored in the file.
In update and delete queries, the path to the index is given so that the
file can be located and perform the tasks.
But, according to the requirements, the metadata file will be stored
separately and all metadata information will be stored in the same file.
The structure will be as follows.
<indexes>
<index collection="path_to_collection_1">
<file>
<path>/home/menaka/xml/catalog.xml</path>
<md5>44AC8A401C32384D9EB00952E1C96685</md5>
<fileName>catalog.xml</fileName>
<lastModified>10/07/2016 23:41:13</lastModified>
</file>
<file>
</file>
.
.
.
</index>
<index collection="path_to_collection_2">
<file>
<path>path_to_collection_2/catalog.xml</path>
<md5>44AC8A401C32384D9EB00952E1C96685</md5>
<fileName>catalog.xml</fileName>
<lastModified>10/07/2016 23:41:13</lastModified>
</file>
<file>
</file>
.
.
.
</index>
</indexes>
In this format, the collection directory is stored separately. But what
really need is the index location. Because, here we already have the paths
for xml documents.
As all indexes are saved in single file and we give path-to-index as update
and delete index parameters, we can retrieve the metadata for xml files
regarding to the given index.
But in this approach we cannot do that unless we store the metadata file
inside the index folder. So, I suggest storing path-to-index instead of
path-to-collection.
The new structure would be,
<indexes>
<index *location="path_to_index_1*">
<file>
<path>/home/menaka/xml/catalog.xml</path>
<md5>44AC8A401C32384D9EB00952E1C96685</md5>
<fileName>catalog.xml</fileName>
<lastModified>10/07/2016 23:41:13</lastModified>
</file>
<file>
</file>
.
.
.
</index>
<index* location="path_to_index_2"*>
<file>
<path>path_to_collection_2/catalog.xml</path>
<md5>44AC8A401C32384D9EB00952E1C96685</md5>
<fileName>catalog.xml</fileName>
<lastModified>10/07/2016 23:41:13</lastModified>
</file>
<file>
</file>
.
.
.
</index>
</indexes>
Thank you very much
