I am releasing version 1.1 and have just pushed several changes to osmosis trunk. These changes don't effect the format, but may require minor changes to software that uses the *.proto definitions.
Although it has been in trunk for a while, this is the first release where the generated C/C++ protobuf code is in package OSMPBF. I am renaming from 'osmbin.jar' to 'osmpbf.jar'. I am licensing the osmpbf source code under the LGPL. As previously discussed, I am removing bzip2 compression and marking lzma compression as a proposed extension, this may require minor changes to existing software. I am renaming the protocol buffer fileformat.BlockHeader to fileformat.BlobHeader (It has a name confusingly similar to osmformat.HeaderBlock.). Software will have to be patched to compile against the new name for this object. I have a conformance file. This file exercises all of the features required to decode the geographic data in PBF files, including offset and granularity. Note that this test is not exhaustive, in particular, it does not currently test the metadata storage (timestamps, version numbers, changeset numbers, etc.) of the PBF format. It is located at the main PBF repository (https://github.com/scrosby/OSM-binary). As it is still a work in progress, invoke crosby.binary.test.BuildTestFile to generate the PBF testfiles. The reference XML output can be generated with osmosis "" osmosis --read-pbf TestFile1-deflate.osm.pbf --write-xml file=- "". To generate the corresponding XML output, you want to use the trunk version of osmosis, which now has deterministic results when metadata is omitted. For the osmosis parser, I am replacing the default date when there is no timestamp metadata in the file. Instead of using the current date, I am using Date(-1). This makes decoding files from pbf to osm deterministic, making it easier to do conformance tests. These changes are now in osmosis trunk. I have also explicitly placed the osmosis pbf code under the Apache 2.0 license (because it contains a disclaimer of liability.) I have tested this code against the old code on the rhode_island.osm extract and only encountered the expected differences in datestamps. If there are any problems, please send me an email. Happy new year to everyone! Scott _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
