Metha-Cat: Support for Paging? about metha

[miku]

I ran into similar issues (too big XML files) in the past and I remember that there are tools addressing this problem specifically; one I remember is xml_split.

On debian/ubuntu it seems to be available with the xml-twig-tools package.

$ metha-sync https://yareta.unige.ch/oai && metha-cat https://yareta.unige.ch/oai | xml_split -l 1 -s 50kb
$ ls -l
total 456K
drwxrwxr-x  2 tir tir 4.0K Jun  1 13:29 ./
drwxr-xr-x 39 tir tir  56K Jun  1 13:28 ../
-rw-rw-r--  1 tir tir  346 Jun  1 13:29 out-00.xml
-rw-rw-r--  1 tir tir  50K Jun  1 13:29 out-01.xml
-rw-rw-r--  1 tir tir  54K Jun  1 13:29 out-02.xml
-rw-rw-r--  1 tir tir  51K Jun  1 13:29 out-03.xml
-rw-rw-r--  1 tir tir  50K Jun  1 13:29 out-04.xml
-rw-rw-r--  1 tir tir  51K Jun  1 13:29 out-05.xml
-rw-rw-r--  1 tir tir  51K Jun  1 13:29 out-06.xml
-rw-rw-r--  1 tir tir  51K Jun  1 13:29 out-07.xml
-rw-rw-r--  1 tir tir  23K Jun  1 13:29 out-08.xml

The resulting XML is valid, but slightly modified:

$ xmllint --format out-01.xml 2> /dev/null | head -4
<?xml version="1.0"?>
<xml_split:root xmlns:xml_split="http://xmltwig.com/xml_split">
  <record xmlns="http://www.openarchives.org/OAI/2.0/">
    <header status="">

Does this help?

PS: Thanks for using metha! I'm just curious (and collecting uses of metha) - if possible, can you share the project name in which metha is used for data acquisition?

@miku Thanks a lot for your answer. We'll try this out!

We are using metha for our linked open research data project Connectome.
