What does CERN do?*

• High Energy Physics (HEP)

• Smash particles together with highly complex machinery like the Large Hadron Collider (LHC).

• Gather data on the smashings and what pops out of them.

• Make conclusions about Life, the Universe, and Everything.

• Central place for HEP. Everyone either comes through here or uses our data.

* (barely) explained by a non-physicist

Experiments on the LHC*

• As particles go shooting around the LHC, instruments at each collision point record data.

• Each of these is an “experiment,” by which we really mean “enormous collaboration.”

• Each experiment gathers huge amounts of data on collisions happening many times each second.

(Just watch the movie: http://cds.cern.ch/record/1125472)

Stuff that makes protons go fast

CMS

ALICE

ATLAS

LHCb

1. Provision

of additional

documentation for the publishe

d results

2. Simplified data formats for analysis

in outreach and training exercises

3. Reconstructed data and simulations as well as the analysis

level software to allow a full scientific analysis

4. Basic raw level data (if not yet covered as level 3 data) and their associated software which allows

access to the full potential of the experimental data

HEP Experimental Data Pipeline• Enormous amounts of raw data

come from the LHC experiments

• Data is progressively processed into smaller pieces

• Disparate data needs are met by a suite of data services

INSPIRE

INSPIRE• http://inspirehep.net

• For literature in high energy physics.

• Included author profiles and citation counts before they were cool.

• De facto career portal.

• Averaged ~321,000 unique visitors per month in 2015.

HEPData

HEPData

• http://hepdata.net

• For supplementary publication data (tip of the iceberg)

• Linked to publication information in INSPIRE

• Includes pre-data-release review functions

CERN Analysis Preservation

CERN Analysis Preservation• https://analysis-preservation.cern.ch/

• code and use cases: https://github.com/cernanalysispreservation

• For storage and access to analysis-level data.

• Captures complexity of data, processing steps, and code, plus peer review and QA.

INSPIRE Upgrade

Unified authentication with ORCID

Unified authentication with ORCID

INSPIRE author profilesAct as personal reference system in HEP (e.g. for assessment and promotion)

Link to data sets (in HEPData)

ORCID works push/pullWorks harvested from ORCID show in “external” tabWorks in INSPIRE pushed to ORCID

HEPData connects to INSPIRE

DOIs – individual and collections• All HEPData records get DOIs.

• Each data table gets a versioned DOI.

• The whole HEPData record is also given a DOI to encompass the whole collection.

Comprehensive data review system
