== Introduction ==
The goals of  the work package ''JRA1 Knowledge Ecosystem Implementation'' are to provide the technology realising the common practices, standards and solutions identified by the NA4 work package and enhance and consolidate the gCube system to match the needs of the ecosystem approach. A primary role of JRA1 (played within ''TJRA1.2'') is to address the various interoperability issues inherent in the construction of a knowledge ecosystem, and then identify and implement proper solutions. Ranging from content-related problems to architecture-oriented issues. Major inputs for this part of the work come from [https://networking.wiki.d4science-ii.research-infrastructures.eu/networking/index.php/Interoperability_Solutions '''DNA4.1'''].

An ''Agilish'' development methodology (referring to no specific Agile development platforms, but to the general idea of quickly responding to change) is driving the teams in JRA1. Plans are sketched and verified with the management boards and user communities; ''seeing and playing with the system'' being the most important thing and preferred to over-planning.

This deliverable documents the gCube technology by reporting on the overall status of the system architecture, the per service tasks and enhancements, and other technical details needed to have a comprehensive understanding of the developed knowledge ecosystem enabling technology. 

The deliverable is implemented through a Wiki page to be easily and promptly adapted to reflect the ever-evolving status of the developed technologies. For the same reasons, performed and planned activities are reported via dedicated TRAC reports, created for this very purpose.

== State of Software Development Activities ==

This section reports on the current maintenance and upgrade activities performed and to be performed on the gCube system. 

Traditional approaches to planning have proved to do not fit Agile methodology. The fast moving forward of the software makes obsolete every plan very quickly and huge documentation should be continuously updated with a considerable waste of effort. The innovative approach followed by D4ScienceII is based upon a proper exploitation of the project's [https://issue.d4science-ii.research-infrastructures.eu/ TRAC instance]:

* firstly, four dedicated milestones were defined:

:* ''Short-Term gCube plan'', used when the activities described in a ticket are planned to be completed within the next month;

:* ''Medium-Term gCube plan'' , used when the activities described in  a ticket are planned to be completed within the next 3 months;

:* ''Long-Term gCube plan'', , used when the activities described in a ticket do not have a starting and ending date yet;

:* ''Ready To Release'', used when the activities described in a ticket are completed and passed to SA.

: The idea behind these milestones is that a developer moves his/her tickets among them according to the work performed or to be performed on each ticket;

* then, JRA1 management asked to each developer to insert his/her own tasks and give an estimation of delivery by assigning one of the milestones above;

* finally, in order to stand over the activities, four TRAC's living reports have been created for this purpose. These reports are introduced in the following sub-sections.

This flexible strategy gives the opportunity to have a living picture of the continuous evolution of the system. The reports are automatically updated each time a change occurs in a ticket or whenever a new ticket is submitted. 

=== Upgrade Activities ===

Upgrade activities refer to tasks and enhancements that lead to future releases of the gCube technology:

&rarr; the planned actions are recorded in [https://issue.d4science-ii.research-infrastructures.eu/report/37 '''report #37''']

&rarr; the closed actions are recorded in [https://issue.d4science-ii.research-infrastructures.eu/report/38 '''report #38''']

=== Maintenance Activities ===

Maintenance activities are dedicated to fix defects found in the technology delivered so far and the related documentation:

&rarr;  the open maintenance activities are recorded in [https://issue.d4science-ii.research-infrastructures.eu/report/39 '''report #39''']

&rarr;  the closed maintenance activities are recorded in [https://issue.d4science-ii.research-infrastructures.eu/report/40 '''report #40''']


In addition to the development activities captured by the reports above, other stems from incidents and malfunctions discovered while exploiting the technology in the production infrastructure. They are captured by two specific living reports, '''current incidents''' ([https://issue.d4science-ii.research-infrastructures.eu/report/9 '''Report #9''']) and '''resolved incidents''' ([https://issue.d4science-ii.research-infrastructures.eu/report/11 '''Report #11''']). Yet, these reports include both JRA1 and JRA2 incidents.

== Code Statistics ==
''This section will report various tables and charts describing the project development.''

[TBC]

== Documentation ==
The software delivered is properly documented by the Development and Administrator's Guides. These two guides represent the main source to obtain information at components level. 

* [https://gcube.wiki.gcube-system.org/gcube/index.php/Developer%27s_Guide Developer's Guide]: this guide targets two audiences:
:* developers aiming at producing software that interacts with a gCube components
:* developers that take over a component from another one and start a new development stream

* [https://gcube.wiki.gcube-system.org/gcube/index.php/Administrator%27s_Guide Administrator's Guide]: this guide is mainly written to provide a support to Site Managers for installing and deploying gCube nodes and components. However, it can be used by developers to have local instances of the components they interact with.

== Software ==

=== Development Version ===
D4ScienceII relies on the [http://etics.web.cern.ch/etics ETICS] system to automate the way its software (gCube and gCore) is built and tested. In particular, the project has put in place mechanisms to perform ''daily builds'' of the latest version of the code committed in the project source code repository. This activity leads to the production of (''i'') a report of the build activity and (''ii'') a set of software artifacts including the software package, the source code and the documentation. 

JRA1 is responsible for managing the development version (namely HEAD) of these reports and artifacts whose main purpose is to provide a way to
* verify the dependencies among the artifacts 
* exchange artifacts among the development teams
