BioXSD | GTrack - A service developed by ELIXIR Norway
It has been confirmed that ELIXIR Norway will further develop and deliver BioXSD and GTrack as a family of interoperable data formats and supportive tools.
The family of interoperable generic data formats for bioinformatics and genomics comprises BioXSD, BioJSON, BioYAML, the tabular GTrack, binary tabular BTrack, and the integrative GSuite, with supportive conversion tools under development.
The aim is to provide a selection of generic, mutually loss-lessly convertible formats suitable for various usage scenarios, such as providing tools, APIs, web apps, or databases, or integrating bioinformatics|genomics data.
BioXSD | BioJSON | BioYAML - Towards a unified data model with multiple serialisation options
BioXSD is a construction site again. Current developments focus on employing XML Schema version 1.1 and JSON Schema, and enabling BioXSD to function as a single data model with multiple choices of tree-based exchange formats (serialisations).
Highest on the priority list is adding JSON and YAML as serialisation alternatives to XML, and implementing smooth interoperability between BioXSD, BioJSON, BioYAML, and GTrack (the unified tabular format for sequence features).
BioXSD version 1.1, release 1.1.3
The next stable minor release of BioXSD 1.1, version BioXSD 1.1.3, was released on the 15th of May, 2015.
As all minor releases of BioXSD are compatible with all previous and future minor releases within the last major version/namespace, the BioXSD 1.1.3 is "backwards and forwards compatible" with all BioXSD 1.1 data instances (i.e. less restricted than the previous versions, and extended with non-mandatory new attributes/elements).
For the list of changes, please refer to the CHANGELOG in the BioXSD-1.1.xsd file.
Developments towards BioXSD version 1.2 (the next major, "backwards incompatible" release) are ongoing in parallel, currently in a pre-implementation stage experimenting with essential design decisions. The 1.2 developments at the moment focus on interoperability with JSON, GTrack, JSON schema, BSON, EXI, RDF (and potentially later also other Semantic Web formats, AVRO/Hadoop, RELAX NG or other alternative schema languages), with the PROV provenance metadata, and migration to XML Schema version 1.1.
BioXSD becoming more "open"
BioXSD 1.1 is now available under a CC BY-SA 4.0 licence! Please note also the new Code of Conduct, outlined in BioXSD-1.1.xsd. In addition, we finally started the long-desired transition to the new source-files repository at http://github.com/bioxsd/bioxsd. We believe that this will bring more transparency to the developments and maintenance of BioXSD, and decrease the friction for participating in the future evolution of BioXSD and related software.
Enhanced and standardised provenance metadata are under development
We are improving the provenance metadata in BioXSD, by implementing a rich but simple model that will be aligned with the W3C PROV standard. It will most likely be part of the next minor release. Thanks shall among others be sent to the OpenBio Codefest 2013 for input and discussions.
For desired additions into the next release, please contact email@example.com.
BioXSD version 1.1, release 1.1.2
A minor release of BioXSD 1.1, the version BioXSD 1.1.2, was released on the 13th of May, 2013.
As all minor releases of BioXSD are compatible with all previous minor releases within the last major release, the BioXSD 1.1.2 is backwards compatible with BioXSD 1.1 data (i.e. less restricted).
For the list of changes, please refer to the CHANGELOG in the BioXSD-1.1.xsd file.
The 50 BioXSD-compatible Web services challenge
Volunteers are still warmly welcome to join the 50 BioXSD-compatible Web services challenge!
The aim is to provide compatible Web services and other tools that adopt BioXSD as one of their input/output formats.
Implementations have already been ongoing at CBS in Greater Copenhagen (Denmark), Rostlab in Greater Munich (Germany), IBCP in Lyon (France), CBU in Bergen (Norway), and at a couple of more sites.
For more details, help, and consultation, please contact firstname.lastname@example.org.
BioXSD is a data model defining exchange formats for basic bioinformatics types of data: sequences, alignments, feature records with associated data and metadata. BioXSD aims to serve as a common, canonical tree-structured format (XML, JSON, YAML, binary) for the basic bioinformatics data. Specialised standard XML-schema formats such as for example SBML, MAGE-ML, GCDML, PDBML, PSI MI MIF, PhyloXML or NeXML are orthogonal efforts and should be used wherever applicable. BioXSD aims at filling the gap between these specialised XML formats.
A canonical data format does not mean "the only format", but an exchange format that can be common to several tools (as one of multiple formats the tools are supporting). Tools can produce and consume BioXSD directly, or BioXSD can be used as an intermediate canonical format, rich enough to enable conversions among diverse formats. Using common exchange format enables smooth integration of compatible tools into analysis workflows.
BioXSD is a rich but not too complicated data model and exchange format, aiming to enable deployment of globally and smoothly interoperable bioinformatics tools on the World Wide Web of Services. BioXSD supports HTTP ("REST") Web services and WS-I compliant SOAP Web services, and interoperates with ordinary HTTP (REST), SOAP, and XML libraries for common programming languages. No other infrastructure than standard HTTP and XML is necessary for using BioXSD-compatible Web services. In the near future, we would like to add smooth support for JSON, YAML, and eventually other data-serialisation languages, as alternatives to using BioXSD in XML.
BioXSD is a "blue-collar" initiative originating from the inside of the bioinformatics community, initiated among others by the EMBRACE project partners and the participants of the 1st DBCLS BioHackathon, in 2008.
The portfolio of standards according to EMBRACE
BioXSD data-type definitions are annotated with EDAM and with a few main Semantic-Web vocabularies. BioXSD thus offers ready-made building blocks for tool interfaces with a globally defined, controlled meaning (semantics).
BioXSD has been developed by analysing existing requirements, tools, Web services, data formats, and ontologies. Feasibility was tested at different pilot providers, using diverse libraries and programming languages.
BioXSD types can be used directly if applicable; or can be included in other standard or custom types, extended or restricted. With tools that use other or proprietary formats, BioXSD can be used as a canonical intermediate exchange format.

BioXSD 1.1 has been developed hand-in-hand with GTrack, the unifying tabular format for sequence/genome features. Both formats use the same tactics for optimising size of diverse kinds of feature records, via flexible options for recording features' positions and other data.
BioXSD 1.1 (namespace
http://bioxsd.org/BioXSD-1.1) is available at http://bioxsd.org/BioXSD-1.1.xsd. This latest stable version is available for implementations, actively maintained, and open to further developments. New requirements and suggestions for changes are welcome and may be reflected in future versions.

(Note: There is no "worked-around" version of BioXSD 1.1 available for SOAP Web service providers using Python ZSI for their backend SOAP stack. It can be made available if required, please contact firstname.lastname@example.org.)
Older BioXSD 1.0 (namespace
http://bioxsd.org/BioXSD-1.0) is available at http://bioxsd.org/BioXSD-1.0.xsd.
(For SOAP Web service providers using Python ZSI for their backend SOAP stack: Due to some important basic features missing in the Python Zolera Soap Infrastructure (ZSI) library, a special version for generating ZSI code is at http://bioxsd.org/BioXSD-1.0.zsi.Workaround.xsd. Do not forget to get the ZSI patch for the empty-complexType bug. This xsd is "SOAP-compatible" with the normal xsd. It means that the services in Python should be generated from WSDLs importing the BioXSD-x.x.zsi.Workaround.xsd Schema, but WSDLs of the deployed services should then be importing the normal BioXSD-x.x.xsd Schema.)
The source files and releases of the BioXSD schema, of supportive utility software, and of documentation are in transition to http://github.com/bioxsd/bioxsd, and will gradually appear there.
