d0cmf
d0cmf – shorted Dušan's zero matrix format
Practical:
- The format for the export of pageviews statitics.
- The export of user pageview statistics:
- group by:
- local wikipedia,
- year,
- date: 2015-07 to 2023,
- public: https://archive.org/search?query=subject%3A%22d0cmf%22
| Original | d0cmf | ||
|---|---|---|---|
| RAW | bz2 | RAW | bz2 |
| 91531991545B | 16923192176B | 8272043931B | 1415546226B |
| 91.5 GB | 16.9 GB | 8.2 GB | 1.4 GB |
| 9% | 8% | ||
- Notice: In a practical comparison, in d0cmf, pagevies are divided according to local wikipedia and thus their size is calculated. Sources: [1] [2].
A bonus for the community (if implemented):
- pageview statistic:
- Smaller compression size of files.
- When saving – support for any long time interval.
- Store statistics divided according to local Wikipedia.
Revision databases
- Otherwise, the storage of site data.
- Revision line encoding: From all revision lines is creating the line index and the revision are then the group of the lines indexes. The line index of revision is stored in the binary format.

| Now | Concept | |
|---|---|---|
| Database | ~19GB | 1 to 5GB (5% to 26%) |
| Export (bz2) | ~2.8GB | ~1.1GB (39%) |
Wiki page language
Idea: to standardize the Wiki page language and to have the convertor wiki ⇒ HTML with DOM and DOM manipulation API.
- Benefits:
- Determining the boundaries where the bot and the user correspond,
- better tools for bots
- one standard, one change tracking document,
- the support of MediaWiki table in the three part software.
