=======================
=== Orthanc Roadmap ===
=======================


=======
General
=======

* Configure an user-defined site UID root if generating DICOM UIDs
  ("FromDcmtkBridge::GenerateUuid()")
* Support "/preview" and "/matlab" for LUT color images
* Improve handling of errors in the command queue:
  https://groups.google.com/d/msg/orthanc-users/--njEbqcDDI/rBu8XL-Mm-cJ
* Support partial file retrieval in Orthanc::HttpClient
* Support retry counter in Orthanc::HttpClient
* Option to enable DNS lookups in DICOM: https://goo.gl/woa35Z


============
Dependencies
============

* Switch from libiconv to libICU (http://site.icu-project.org/download),
  as recommended by Boost:
  http://www.boost.org/doc/libs/1_64_0/libs/locale/doc/html/building_boost_locale.html


=============
Documentation
=============

* Document REST API with Swagger/OpenAPI


========
REST API
========

----------
Short-term
----------

* Create multi-frame images with /tools/create-dicom (by adding a
  "MultiFrame" flag to avoid creating a series)
* In the /studies/{id}/anonymize route, add an option to remove secondary captures.
  They usually contains Patient info in the image.  The SOPClassUID might be used to
  identify such secondary captures.

---------
Long-term
---------

* Stick to the JSONapi or JAREST guidelines for a "v2" of the API:

  http://www.admiraalit.nl/jarest/


=====
DICOM
=====

----------
Short-term
----------

* Support C-GET: 
  http://dclunie.blogspot.be/2016/05/to-c-move-is-human-to-c-get-divine.html
* Check Big Endian transfer syntax in ParsedDicomFile::EmbedImage and
  DicomImageDecoder

---------
Long-term
---------

* Support DICOM TLS (cf. "--enable-tls" in storescp)
* Support Storage Commitment:
  https://groups.google.com/forum/#!msg/orthanc-users/VZOn8St65jw/s8kg_OHesj0J
* Support extended association:
  https://groups.google.com/d/msg/orthanc-users/xD4d3mpc6ms/srF7E2goAAAJ

---------
Encodings
---------

* Support multiple specific character sets (cf. "SCSH32" in orthanc-tests)
  - http://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_C.12.html#sect_C.12.1.1.2
  - Japanese test: http://dicom.nema.org/MEDICAL/dicom/2017c/output/chtml/part05/sect_H.3.2.html
* Support Supplementary Kanji set (ISO 2022 IR 159)


=======
Plugins
=======

---
SDK
---

* Image transcoding API
* Add plugins for normalized operations (notably so as to support
  Print SCU/SCP):
  https://www.medicalconnections.co.uk/kb/DICOM_Print_Service
* Provide access to the Orthanc::DicomUserConnection class in plugins:
  https://groups.google.com/d/msg/orthanc-users/ycDA1xPuTRY/nsT2_GOtEgAJ

----------------
Ideas of plugins
----------------

* DICOM-RT primitives (RT-STRUCT, RT-PLAN, RT-DOSE)
* Converter to/from NIfTI
* Decode JPEG2k with grok: https://github.com/GrokImageCompression/grok
* Generate dynamic HTTP content using Lua:
  https://groups.google.com/d/msg/orthanc-users/KompazkxRSs/5Rh03mzgDAAJ
* More generally, expose more callbacks of the plugin SDK in Lua:
  https://groups.google.com/d/msg/orthanc-users/_FbiRHuXPGM/J-OAv7zaCAAJ
* Authorization plugin for the DICOM protocol:
  https://groups.google.com/d/msg/orthanc-users/Wv-QEwTE0IA/rvJxoOjcAQAJ


===
Lua
===

* Configure HTTP headers from Lua (in HttpGet(), HttpPost(),
  HttpPut(), HttpDelete(), RestApiGet(), RestApiPost(), RestApiPut()
  and RestApiDelete().
  https://groups.google.com/forum/#!msg/orthanc-users/WNnW187OILM/6XX_bm96BwAJ


===========
Performance
===========


================
Code refactoring
================

* Use Semaphore::Locker everywhere (instead of explicit
  Release() and Acquire())
* Avoid direct calls to FromDcmtkBridge (make most of its 
  methods private), go through ParsedDicomFile wherever possible

=================
Platform-specific
=================

---------
Packaging
---------

* CentOS and RHEL through EPEL:
  http://fedoraproject.org/wiki/EPEL_Package_Maintainers

------------------------
Big-endian architectures
------------------------

* Check the generated 16bpp PNG images

-----------------
Microsoft Windows
-----------------

* Add compatibility with non-ASCII paths (Orthanc expresses its paths
  as UTF-8 strings, but Windows expects them to be translated to the 
  system locale)


=====================
External applications
=====================

* Create REST bindings with Slicer
* Create REST bindings with Horos/OsiriX
