UI: "For Education" vs "For Research"

[tiborsimko]

When visitors click on "For Education" and on "For Research":

• http://opendata.cern.ch/education
• http://opendata.cern.ch/research

they may actually wonder what has changed? This is because the page content is largely the same, modulo introductory phrase.

This does not feel like it merits a new page... Hence it would be good to present clearly different kind of information in various sections in order to "justify" having two entry points.

Some possibilities:

• use different illustrative images, more serious in "research", e.g. bits of code, e.g. running ROOT;
• kill introduction to experiments in "for research", where it should not be needed, and rather display something "more deep", e.g. say something upfront about stored datasets (e.g. no MC);
• consider introducing even more aggressive distinction between education and research, e.g. keep only "big datasets" in the Research area (which would give floor to only CMS right now...)

@katilp @mgheata @RaoOfPhysics What do you all think?

I see the point- I'm in favour of your second point, i.e. "kill introduction to experiments in "for research", where it should not be needed, and rather display something "more deep", e.g. say something upfront about stored datasets (e.g. no MC);"

For CMS, the text could be something like: CMS is releasing data in the same format as used in data analysis by CMS physicists. A CMS-specific analysis framework is needed, and it is provided as a Virtual Machine image with the CMS analysis environment. The data can be downloaded (be aware of the large size of the datasets) or accessed directly through the VM image. Basic information of the data contents is provided in http://opendata.cern.ch/about/CMS and in http://opendata.cern.ch/about/CMS-Physics-Objects. The original data are in primary datasets, i.e. no selection nor identification criteria have been applied (apart from the trigger decision), and these have to be applied in the subsequent analysis step. For the first release, no simulated Monte Carlo datasets are provided

@tiborsimko @RaoOfPhysics comments, correction?

I am also in favour of your second point For ALICE: These ALICE datasets contain a sample of events from the p-p an PbPb LHC runs in 2010, in the ESD (event summary data) format of the ALICE reconstruction program. The events are unbiased and are not a result of event selections and this format is directly usable by the analysis done by ALICE physicists. The data can be downloaded and used from a specific ALICE virtual machine image which can be installed using this procedure (link) and which demonstrates some ALICE analysis and event display examples. A single dataset is exposed in the form of a custom VSD (V0 summary data) format which is not usable in normal analysis but just by a set of masterclasses available also from the ALICE VM. For the first release, no simulated Monte Carlo datasets are provided.

Please check #314 (maybe we can close it and continue here). The current text is the same, but we need (in total) 4 pieces of text per experiment.

1. Education: landing tab
2. Education: experiment tab header
3. Research: landing tab
4. Research: experiment tab header.

Right now we have:

1. Education, landing tab: CMS The CMS (Compact Muon Solenoid) experiment is one of two large general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN in Switzerland and France. The goal of CMS is to investigate a wide range of physics, including properties of the recently discovered Higgs boson as well as searches for extra dimensions and particles that could make up dark matter. ALICE ALICE (A Large Ion Collider Experiment) is one of seven detector experiments at the Large Hadron Collider at CERN. The other six are: ATLAS, CMS, TOTEM, LHCb, LHCf and MoEDAL. ALICE is optimized to study heavy-ion (Pb-Pb nuclei) collisions at a centre of mass energy of 2.76 TeV per nucleon pair. The resulting temperature and energy density are expected to be high enough to produce quark–gluon plasma, a state of matter wherein quarks and gluons are freed. Similar conditions are believed to existed a fraction of the second after the Big Bang before quarks and gluons bound together to form hadrons and heavier particles.

2. Education: experiment tab header CMS Needs to be provided ALICE Needs to be provided

@pamfilos Can you modify already known text so that we progress in steps?

[RaoOfPhysics]

@pamfilos: If you haven't started on this yet, I'll edit the text directly into the websearch.py file as I have it open and ready to go.

[katilp]

Any progress on this? The CMS intro is still the same, we should at least have the case 3) above for research.

[RaoOfPhysics]

@katilp: This is my TODO but I haven't had time to take care of it so far in India. Will try and sort it out tomorrow.

[RaoOfPhysics]

@tiborsimko: Given the change to the education and research sections (and the new text already on the home page), does this issue still need addressing or can it be closed?

[tiborsimko]

We can close it if the intro text was already updated everywhere. (I have not double checked.)

[RaoOfPhysics]

@tiborsimko: Looks like it has been changed on http://opendata.cern.ch/#rsch, http://opendata.cern.ch/#edu, http://opendata.cern.ch/education and http://opendata.cern.ch/research. Someone else should also confirm!

But what I meant was that the scope of the text and layout has changed, so we no longer need the text to be as required above. Namely:

• Education has a generic introduction to the section while the experiment tabs introduce the experiments (and not their data with an educational scope)
• Research has a generic introduction to the section while the experiment tabs talk about the experiment-specific data and tools released for research

(Sorry about poor wording.)

[suenjedt]

@RaoOfPhysics thats also my understanding. @espacial and @pamfilos: can you confirm?

[espacial]

It can be closed. The current (final?) text is based on this issue and includes the comments scattered around the others.

[RaoOfPhysics]

@espacial: I suspected as much, thank you for confirming. :)
