Assumptions
onsolidated facts:
 Very rich applications and data collections are currently maintained by a
multitude of authoritative providers
 Different problems require different execution paradigms: batch, map-
reduce, synchronous call, message-queue, …
 Key distributed computation technologies exist: grid (gLite and Globus),
distributed resource management (Condor), clusters (Hadoop), …
 Several standards are adopted in the same domain
ocietal observations
• A rich variety of protocols, models, and formats
• Create barriers in the usage of resources
• Delay dramatically new exploitation patterns
echnical observations
 Protocols, models, and formats heterogeneity increases load,
 Load increases failures

D4Science Vision
4Science objectives:
hide heterogeneity, i.e. abstract over differences in location,
protocol, and model;
embrace heterogeneity, i.e. allow for multiple locations,
protocols, and models;
echnical goals
 no bottlenecks: scale no less than the interfaced resources
 no outages: keep failures partial and temporary
 autonomicity: system reacts and recovers

Why sharing through VREs is a key?
T
hrough the VRE, groups of users have controlled access to
distributed data and services integrated under a
personalised interface.

Why sharing through VREs is a key?
Virtual Research Environment (VRE) supports cooperative
activities
 Metadata cleaning, enrichment, and transformation by exploiting
mapping schema, controlled vocabulary, thesauri, and ontology
 Processes refinement and show cases implementation (restricted to a
set of users);
 Data assessment (required to make data publically exploitable by VO
members);
 Expert users validation of products generated through data elaboration
or simulation.

Why sharing through VREs is a key?
REs integrated environment put at disposal a functionality
set to support and perform research activities:
 the ability to integrate heterogeneous data and services
 the ability to process information on-demand ingesting the
results,
 to share data and process with other users,
 to customize collection of information,
 to store user actions and exploit them for further use,
 to aggregate relevant information into ad-hoc information
sources and keeping them updated.

quaMaps is an application*
 tailored to predict global distributions of marine species
initially designed for marine mammals and subsequently
generalised to marine species,
 that generates color-coded species range maps using a
half-degree latitude and longitude blocks
 by interfacing several databases and repository providers

quaMaps execution is based on the gCube Ecological Niche
Modelling Suite which allows the extrapolation of known species
occurrences
Species Distribution Maps Generation
◦ to determine environmental
envelopes (species tolerances)
◦ to predict future distributions by
matching species tolerances
against local environmental
conditions (e.g. climate change
and sea pollution)
Very large volume of input and output data: HSPEC native range 56,468,301 - HSPEC suitable range 114,989,360
Very large number of computation: One multispecies map computed on 6,188 half degree cells (over 170k) and 2,540 species
requires 125 millions computations (Eli E. Agbayani, FishBase Project/INCOFISH WP1, WorlFish Center)

 JISC - King’s College London
 Look at new ways of integrating existing data resources for Classics and
add services so that research work based on integrated resources can be
published
 Data sources
 The Heidelberger Gesamtverzeichnis (HGV) der griechischen Papyrusurkunden
Aegyptens, a collection of metadata records for 55,000 Greek papyri from Egypt.
 Projet Volterra, a database of Roman legal texts, and associated metadata, from
various sources (epigraphic, papyrological, or literary) currently in the low tens of
thousands but very much in progress.
 The Inscriptions of Aphrodisias, (InsAph), a corpus of about 2,000 ancient Greek
inscriptions from the Roman city of Aphrodisias in Asia Minor, including transcribed
texts and metadata marked up using EpiDoc TEI, as well as images of the physical
objects.
 Main functionality
 cross-collection search
 workspace
 annotation

VRE Sumamry
4Science approach:
• Heterogeneous resources are accessible in a common
ecosystem of resources
• despite their locations, technologies, and protocol
• Different communities have access to different views
• according to the conditions under which the sharing can occur
• Each community can define its own virtual research
environment to satisfy specific needs
• for a limited timeframe and at no cost for the providers of the
resource
• Several virtual research environments can coexist
• without interfering each other even by competing for the same
resources

nteroperability approaches are key to exploit such richness
4Science offers a variety of patterns, tools, and solutions
 to interconnect
 Heterogeneous digital content
 Heterogeneous repository systems
 Heterogeneous computation platforms
with a rich set of free-to-use tailored services
 to decrease the cost of adoption
 to reduce the time to market of new ideas
 to deal with plethora of standards
