[jira] [Updated] (TIKA-1423) Build a parser to extract data from
GRIB formats
[ https://issues.apache.org/jira/browse/TIKA-1423?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lewis John McGibbney updated TIKA-1423:
---------------------------------------
Attachment: TIKA-1423v2.patch
Patch for trunk which passes all tests including issues experienced with bundle module. Some investigative work was required here as well as publishing [Unidata dependencies|http://search.maven.org/#search|ga|1|ucar] to Maven central and updating our [https://wiki.apache.org/tika/ThirdPartySonaType|wiki documentation].

> Arctic dataset contains a MIME format called GRIB - General
> Regularlydistributed information in Binary form http://en.wikipedia.org/wiki/GRIB . GRIB is a well known data format which is a concise data format used in meteorology to store historical and
> weather data. There are 2 different types of the format GRIB 0, GRIB 2. The focus will be on GRIB 2 which is the most prevalent. Each GRIB record intended for either transmission or storage contains a single parameter with values located at an array of grid points, or represented as a set of spectral coefficients, for a single level (or layer), encoded as a continuous bit stream. Logical divisions of the record are designated as "sections", each of which provides control information and/or data. A GRIB record consists of six sections, two of which are optional:
>
> (0) Indicator Section
> (1) Product Definition Section (PDS)
> (2) Grid Description Section (GDS) optional
> (3) Bit Map Section (BMS) optional
> (4) Binary Data Section (BDS)
> (5) '7777' (ASCII Characters)
