=== article metadata === | === article metadata === | ||
Similar to global meta data for individual articles can be included. Devices and special readers will only use the actual article content which is already stored in the A namespace. If needed the ZIM creator can add individual meta data as kind of a template for each article in the B namespace, under the same name as the article. When the reader application initializes the ZIM interface in the zimlib it can set if it wants to retrieve the pure article content from namespace A or the processed content of namespace B including the article content. This way maximum flexibility for the reader application is kept. | |||

Currently the integer compression from the [[Zeno File Format]], QUnicode has been used in ZIM as well. For the new indeces we want to look into alternatives that obey a standard, the UTF-8 compression could be a good choice. | |||
The details have to be set during development as well as the places where to use it. In general all integer compression in ZIM will use the same method to be consistent. | |||
=== lzma compression === | === lzma compression === | ||
A new compression method using LZMA algorithm will be introduced. This is long-planned but there was not library for a long time. Now there are ''lzma-utils'' and ''xz-utils'' available, still in development but we want to give it a try now. | |||
We expect a much better compression ratio and a faster decompression which would improve the usability on small devices as LZMA is focusing on easy uncompression. | |||
