Subject [jira] [Closed] (SIS-164) Create a "sis-tika" module
Date Sat, 05 May 2018 10:13:00 GMT


Martin Desruisseaux closed SIS-164.
    Resolution: Not A Problem
      Assignee: Martin Desruisseaux

The relationship between Tika and SIS is rather the other way around: SIS can be one source
of metadata (among many others) for Tika, while Tika is not a source of geospatial data for
SIS (Tika itself relies on other libraries for geospatial data).

> Creates a {{sis-tika}} module as a bridge between Apache SIS and Apache Tika. Tika is
a generalized content detection and analysis library. One of its key components is a generic
metadata container, that is typed. Tika can work before Lucene in order to represents data
from various sources (PDF, Office, TIFF, etc.) in a uniform way that Lucene can index, but
isn't dependent on Lucene.
> The most obvious SIS parts that can be linked to Tika are the {{org.apache.sis.metadata.iso}}
packages. This SIS metadata module addresses specifically the ISO 19115 metadata, while Tika
is more generic. Consequently we should be able to map all SIS metadata to Tika, but the converse
may not be always possible.
