Hi Fabrice,

Thanks for your response to Vladimir.

You are completely right, BaseX has its own compression algorithms
(without compression, databases would be much larger). Due to the
query update facilities and additional index structures, a database
will always cosume more space than zipped XML documents.

Cheers
Christian

Hi Vladimir,

If your question is : is there a compression option to reduce database files 
and use built-in index features ? the answer is no.
I can remember that BaseX use custom compression for text nodes. [1]

Christian, I hope you are doing well ?
Did I loose my mind or Did BaseX have a long time ago a compressed database 
option ?

I am not sure if I understand. How do you proceed? Could you possibly
give us a step-by-step explanation?

Re: [basex-talk] Forcing reading _only_ from standard input

[Christian Grün]

Hi Richard,

Newlines (i.e., whitespace-only, non-empty strings) were treated
identically to the "." file reference. As you can also supply absolute
and relative file and directory paths as arguments for the -i flag,
the factbook.xml file, which is located in a descendant directory of
your current directory, was opened instead and bound to the context
item.

This special case will now be checked. In addition, the error message
for empty strings will now be suppressed. Feel free to check out the
latest stable snapshot [1].

Best,
Christian

I can compress xml-data and store it in db.But then how can I search inside that db using index? Is it possible? 22.08.2018, 17:28, "Christian Grün" : Because of the size, is there a way to store xml-data as archiveIf you want to compress your XML documents with XQuery, you can have alook at the Archive or ZIP Module of BaseX.

If you want to compress your XML documents with XQuery, you can have a
look at the Archive or ZIP Module of BaseX. I am not sure, however, if
this is what you are looking for?

> (with possibility to search) ?

The BaseX implementation of fn:doc() and fn:collection() supports
zipped files as arguments. The contents will be unzipped
automatically:

  collection('my-xml-files.zip')

If you create databases, you can specify ZIP files as input, too.

Re: [basex-talk] basex 9.1 and websockets

[Christian Grün]

Hi Max,

I think we can provide a version in September which will be stable for
testing. If you want to have a look at the current (alpha) version,
feel free to follow the steps described by Johannes in GitHub [1]. Any
feedback is welcome.

Cheers
Christian

Hi,

how far are we from the wss enabled release?

I am ready for beta testing ;-)
