Introduction


We are starting
DRIS (Directory of Research Information Systems)

development from a collection of
descriptions

for already implemented CRIS
. Then we
o
pen
a
registration of CRIS artifacts connected with
DRIS records of parent CRIS.
To register the "content" type artifacts we will use CERIF list of entities
(Projects, Persons, Organizations, Funding, Outputs {products, patents, and publications}, Events,
Facilities, Equipment, Services, etc.). The second type of the
CRIS
artifacts is "software". In cooperation
with Architecture TG we will make a list of
classes

of this type of artifacts.
As a result
CRIS community

will
have
a catalogue of information about

existed CRIS with details about its content a
nd used software.
The catalogue

can be updated
and expanded
in decentralized mode.

Next w
e extend
the
content type of
CRIS artifact specification by adding fields for

harvesting gateway
's

parameters

(
UR
L
, proto
col and available formats
)
.
Stored at DRIS
harvesting gateways

data

will be

rearranged as an information hub

subsystem
, which is open for input (any organization can
register

content artifacts and their
harvesting
gateway
parameters
) and
for
output (any us
er
or a software robot
can take

free

at DRIS the
gateways' parameters to harvest open metadata

from their source CRIS
).

DRIS
information hub will
provide a CERIF
-
XML interoperation mechanism
and
allow
s

a multiple
reuse of
standardized
metadata

outside DRIS
.


As a human navigation and searching interface to the
DRIS
information hub we can
visualize integrated
metadata as

a Pan European research portal.

This development from the basic DRIS to the Pan European
research portal with optimistic view can take abou
t 2
-
3 years.

And we have very perspective lines for the further DRIS development.

When

we have at DRIS
some artifacts
collections
(
content and software
types)

we can provide for
euroCRIS members or wider


for international CRIS community


a tool

to
use

the
artifacts

and operate
with them in some innovative forms
.
E.g.
all available artifacts can be using as a building kit

for
expressing
ideas,
for
designing
logical
/structural

models and
making
proposals
of

new
CRIS content

and
services
.

Thus proposals

wi
th assigned intellectual rights of its authors
can be
publicly exposed for
implementing

by some
developer's
organization or as a
CRIS
community project on a base of
have
existed
artifacts
.

Technically th
u
s logical
/structural

modeling
that us
e
d

the

DRIS ar
tifacts can be
support
ed
by a tool for
semantic linking

of

selected artifacts.

Where the semantic is carrying a sense and explanations about an
author's idea
, but

the linkages express a scope and a structure of involved artifacts.

Since DRIS is based
on a
federation principle (
data
can
be
change
d by

only
its owner or authorized person
),
the
linkages
data should be stored outside

the

linking objects. To support semantic linkages between DRIS artifacts
we
should create a special system. Initially we
called
it

SLOR
(Semantic Linkages Open Repository)
.
However such tool can be implemented differently, e.g. it can exist as a subsystem of a CRIS
.

Members of CRIS community can express their creativity ideas by linking semantically DRIS artifact.
Created linkages a
re stored at SLOR. DRIS information system
makes a request to SLOR
when
a user
opens

some
DRIS object for viewing.

DRIS
gets back
from SLOR
the data about existed linkages for the
displayed

object and
can
visualize
all
ingoing/outgoing linkages
at
the obje
ct
's web page
.

If we have both: (1) DRIS information hub as a virtually integrated source of research content, and (2) a
tool to express ideas about reuse and development of the content and software artifacts belonged of
some CRIS, we can establish a virtu
al research environment where
all free available for harvesting
content's metadata will
be
visualize
d like research Data and Information S
pace
(DIS) and all proposed
tools and services can be connected with DIS objects using some r
esearch e
-
infrastructure.

By this way

we get a
reincarnation

of the mentioned above Pan European research portal, but in a more useful
form


as a virtual research environment.

DRIS development stages


1. Basic DRIS


Basic DRIS

main functions are: (1) t
o register
descriptions of already implemented
CRIS
at

DRIS
database

and (2) to v
isualiz
e

this data as a catalogue
at euroCRIS web si
te.


Proposed initial tasks:


1.

To d
iscuss ne
cessary
fields to register CRIS

at the basic DRIS
, see the current input form
-

http://www.eurocris.org/DRIS_Form.php

2.

To determ
i

e

what end
-
u
ser interfaces
should has the

DRIS database (to edit records, to
search
and
display records)

3.

To discuss
euroCRIS and/or CRIS community strategic goals related with DRIS

and how
to make
DRIS
more
useful






5

2. DRIS as a federation of CRIS related information objects


As the first step to more useful DRIS we propose to build a

registration of CRIS components (artifacts) as
separate information objects. A CRIS artifact is a part of a CRIS content or software that can be reused in
some form by CRIS community members. Registering CRIS artifacts at DRIS means that the artifacts are

involving into professional circulation and reuse under certain terms.

2.1. Proposed initial tasks:


4.

To have a list of possible CRIS ar
tifacts types/classes (in cooper
ation with CERIF TG and
Architecture TG). Initial
ly

proposed version of the CRIS artifac
ts types/classes

is listed below and

is

published at the forum.

5.

To define a set of fields for CRIS artifacts description. Matching a format and a structure of this
set with CERIF entities (cfResProduct?). Adding to the set some special fields to specify
ha
rvesting
/usage

parameters of the artifact.

What kind of usage can exist for "software" type
artifacts

and how it should be specified at the input form
?

6.

To decide on practical implementation of the CRIS artifacts database (at euroCRIS web site or
outside) a
nd on forms of its integration with DRIS database and web interfaces.

7.

To set
up
rules for users of DRIS

+

CRIS artifacts system. If thus extended DRIS is a federation of
information objects, how can not owners connect artifacts with DRIS records?

3. DRIS as an Information H
ub


W
e
have within a
CRIS artifact specification
the

field
s for harvesting gateway's parameters (URL,
protocol and available formats). Stored at DRIS harvesting gateways data
can

be

rearranged as an
Information H
ub

(IH)

subsystem
.

IH

is open for input (any organization can register content artifacts and
their har
vesting gateway parameters) and for output (any user or a software
agent

can take free at DRIS
the gateways' parameters to h
arvest open metadata from the
source CRIS). DRIS information hub will
provide a CERIF
-
XML interoperation mechanism and allows a mult
iple reuse of standardized metadata
outside DRIS.


7

Proposed initial tasks:


8.

A discussion of the DRIS IH's
CERIF
-
XML interoperation mechanism
, main features and added
value

9.

Technical and information architecture of the DRIS IH and its main utilities

10.

Informa
tion Hub's input/output protocols (enhanced
OAI
-
PMH, RSS, etc
.)

11.

Visualization of the DRIS IH content as Pan European research portal

3.1. Information Hub instances: a list of URLs or a database


The simplest version of the IH can exist
just
as a list of UR
Ls
filtered from extended DRIS with
harvesting
parameters. But thus IH can not guarantee a proper work of CERIF
-
XML interoperation mechanism. So
the further DRIS development demands a more complicated IH design.


IH should
keep integrated content in
a dat
abase
.

A software that operates as
IH

input utility
takes

in
automated mode all available
metadata
according the list of

URLs mentioned above as the simplest IH.
The
collected
metadata
can be improved on a "fly" to match the CERIF data model and can be
sto
red
in
some database. The IH database
100% CERIF compatible
content should be regularly synchronized
(everyday)
with
the
content of the source CRIS artifacts. Another software that operates as HI output
should
allow
a
retrieving
of
the content by

some quer
y
language.

Full IH content should be visualized as
e.g. Pan European research portal.


3.2.
Information Hub

input/output protocols


The input/output protocols should allow a retrieving of collected metadata according two main
structur
es
:

(1) organizationa
l hierarchy, and (2) scientific hierarchy.


(1) community
(retrieve all metadata belonged to some community

or a group of organizations
)

-
> organization
(retrieve metadata belonged to some organization)

-
> section (data type)
(retrieve all metadata belonge
d to some data type, e.g. all
persons)

-
> collection
(retrieve all metadata belonged to some collection)

-
> object

(retrieve a metadata belonged to some object)

(2) scientific discipline


-
> scientific theme (line)


-
> section (data type)

-
> collection

-
> object


If we use
the
popular OAI
-
PMH
and/or RSS protocols "as is", we are

not able to make retrieving
according
listed

hierarchical structures.


The TG should propose a way to enhance existed popular protocols or should design a special protocol
for i
nput/output operations with DRIS IH.


3.3. C
onversion utility



8

Some organizations
can
have
CRIS

artifacts
with storage models that are not CERIF
-
compatible.
However, such organizations can
use a conversion utility to

change
(e.g.
on a "fly"
)

their CRIS
ar
tifacts
'

format to CERIF. Th
e conversion utility can work on

the side of organization (it can work behind the

harvesting URL), as well, as on

the side of DRIS IH (
a
harvesting metadata from the organization will be
processed
first
by the
conversion
utility

at IH input). S
o
within IH this metadata

appears as a
pure
CERIF
with respect to queries, responses and information exchange.

.
Information Hub content visualization: Pan European research portal


Initially DRIS
is required to improve visibility
of alr
eady implemented CRIS, but when DRIS IH is
integrating metadata of many CRIS
,

it

can also work as a form

the technical underpinning for the
operation of the
research information
portal.

The DRIS IH is designed for communication with software
agents (gatewa
ys and harvesters), but thus
Pan European research portal

can provide a human
navigation and search

interface to the
integrated metadata
.

4. DRIS
+ SLOR


SLOR (Semantic Linkages Open Repository) as a tool to create semantic linkages
between

information
obj
ects belonged to DRIS (CRIS descriptions, artifacts) and also to external information systems (web
pages of person and organization profiles, articles

of the Best Practice catalogue

and
other materials on
the web
)
.



If we have at DRIS some artifacts colle
ctions (content and software types) we can provide for euroCRIS
members or wider


for international CRIS community


a tool

to
use

the artifacts

and operate with
them in some innovative forms. E.g. all available artifacts can be using as a building kit

fo
r expressing
ideas, for designing logical/structural models and making proposals of new
CRIS content

and services.
Thus proposals
with assigned intellectual rights of its authors
can be
publicly exposed for implementing

by some developer's organization or
as a CRIS community project on a base of
have existed
artifacts.


Technically thus logical/structural modeling that used the DRIS artifacts can be supported by a tool for
semantic linking of selected artifacts. Where the semantic is carrying a sense and e
xplanations about an
author's idea, but the linkages express a scope and a structure of involved artifacts. Since DRIS is based
on a federation principle (data can be changed by only its owner or authorized person), the linkages
data should be stored outsi
de the linking objects. To support semantic linkages between DRIS artifacts
we
have to

create a s
pecial system. It is the first initial release

called SLOR (Semantic Linkages Open
Repository).

Members of CRIS community can express their creativity ideas b
y linking semantically DRIS artifact.
Created linkages are stored at SLOR. DRIS information system makes a request to SLOR when a user
opens some DRIS object for viewing. DRIS gets back from SLOR the data about existed linkages for the
displayed object and

can visualize all ingoing/outgoing linkages at the object's web page.

Proposed initial tasks:


12.

A new model to operate with CRIS artifacts: connecting them by semantic linkages.
How
it

can

make DRIS mor
e useful and create

added value
s

for
the
CRIS communit
y
?

13.

What semantic vocabularies will be needed to express possible classes of relationships between
information objects, including DRIS records, CRIS artifacts and related objects of external
information systems?

What
kinds of relationships make

sense to ex
press and visualize?

14.

Rational m
odels
o
f semantic linking instrument
’s design and practical implementation
:
as a
SLOR
or
as a
CRIS.

15.

Extended DRIS as a platform for modeling and designing new CRIS artifacts.
A virtual
environment for p
rofessional interaction
s among members of CRIS community
, including tools
for

expressing ideas, for designing logical/structural models and making proposals of new
resources and services.

Below we provide some SLOR technical details, but as a more general system than semantic li
nking of
DRIS information objects, including CRIS artifacts. It is described as a tool to create and manage
semantic linkages between any information objects of research DIS, where DRIS objects is just a subset
with specific semantic vocabularies.

4.1. An
idea of semantic linking tool


We can design a tool for researchers to express their opinions about existed relationships between DIS
objects in visual and computer
-
readable forms. It can be realized as a specific open repository, which
will allow any rese
archer to create semantic linkages caring by semantic a relationship data

between DIS
objects, to store, manage and accumulate semantic linkages, to provide navigation and searching tools
over a set of accumulated linkages. This repository should have some

API, e.g. to provide data about
linkages on request to external CRIS for visualization of a network of linkages composed of articles and
other information objects belong to this CRIS. And the repository of course should have advanced
interoperability feat
ures to exchange linkages data with other repositories and CRIS.

4.2. Semantic vocabularies


In designing this open repository there is a challenge with providing complete and proper linkages'
semantic for covering all types of relationships that scientis
ts
, including CRIS community,

can wish to
express for linking objects of research DIS. A background for creation necessary semantics vocabularies
includes: a semantic section of CERIF (Common European Research Information Format),
recommendations of W3
-

S
KOS (Simple Knowledge Organization System), SWAN (Semantic Web
Applications in Neuromedicine), SPAR (Semantic Publishing and Referencing Ontologies) and especially
its parts CiTO (Citation Typing Ontology) and DoCo (Document Components Ontology).


As the i
nitial release
we
propose

following types of scientific relationships and associated semantic
vocabularies (source
of
semantic
s

are
in brackets):



Inference (CiTO): obtain background from, updates, used as evidence, confirms, qualifies



Impact/usage (CiT
O): contains assertion from, uses data from, uses method from, corrects,
refutes



Hierarchical and associative (SKOS, SWAN): broader, narrower, related, alternative to



Components of scientific composition (DoCo): duplicate, revised, etc.


There are also

other types of relationships, like "professional opinions", "personal
-
organizational
relationships" and so on.

4.3.
Proposed
SLOR
design


Semantic Linkages Open Repository (SLOR) is a tool to expand current research DIS by a new type of
objects: "linkage"
. The "linkage" data type is designed to carry out the subjective opinions of scientists
about the relationship that exists between any pairs of DIS objects, including "person", "organization",
"project", "research result", "event"
, "artifact"

and some oth
ers. Rendered scientific relationships
include: (1) relationships between the various research

and development (R&D)

outputs like inference,
usage, impact, comparison, etc; (2) relationships between elements of the set {scientists, organizations};
(3
) rela
tionships between R&D

outputs on the one hand and elements of the set {scientists,
organization} on the other.



10

The "linkage" data type is based on CERIF Link entity specification. It allows for the specification of a
source and a target objects by their
IDs. Thus, all linkages are oriented from a source object to a target
one. A pair of objects IDs is complemented by semantic value, which characterizes a type of relationship
between objects. Possible semantic values are organized as a set of semantic voca
bularies according
types of scientific relationships.


For practical using in SLOR we extended the initial CERIF Link entity model by adding:




the linkage's ID, since the linkage exists as a research DIS object and has to have unique ID;



a field for
comments;



the creator of the linkage.


SLOR openness means: a) it is free to use, i.e. any scientist can use it to create semantic linkages
between any available objects of research DIS (proposals are moderated); b) all semantic linkages in
SLOR are ope
n for harvesting and external using by other research information systems; c) openness of
multiple semantic vocabularies for replenishing and development (proposals are moderated); d) DIS
data types, which objects can be linked in SLOR can be expanded.


SL
OR functionality includes a personal zone, a public portal for navigation and searching over
accumulated linkages, and some other services (information hub, monitoring of linkages' changes,
sending notifications, building scientometrics, etc.).


For bette
r SLOR navigation and searching the IDs of source and target objects are supplemented in the
repository by name/title and data type of the objects. To get this information in an automated mode
from the DIS we assume that source/target objects metadata are
available through RSS or OAI
-
PMH
protocols and have CERIF, ReDIF or some other popular formats.


Any external CRIS can in an automated mode check presence in SLOR of linkages for own information
objects. If positive, the linkages' data can be harvested fro
m SLOR to the CRIS using API. So external CRIS
can visualize a network of linkages composed of articles and other information objects belong to this
CRIS.

4.4. SLOR benefits


With SLOR researchers have a new tool and new professional dimension for scientif
ic creativity as well.
Additionally to traditional way of scientific work now they can express new scientific knowledge about
relationships between separate research results by building multilayer networks of semantic linkages.


Scientists can create now t
heir research publications in a style of semantic networks. E.g. by linking
separate research objects, "units of thought" or other types of research outputs, which can belong to
different authors. As a result, SLOR improves a scientific circulation mechani
sm and research outputs
(nodes of semantic networks) can be easily reused by the research community.


SLOR notifies scientists about linking/using their research outputs, as well about changes in research
objects that they linked with own outputs. It impr
oves research communication and increase efficiency
of research work at large.


SLOR provides new scientometrics based on qualitative data about scientific relationships, like impact,
usage and others. It can help with research assessment and evaluation a
nd it improves the professional
signaling system of the scientific community.

If we have both: (1) DRIS information hub as a virtually integrated source of research content, and
(2) a
tool to express ideas about reuse and development of the content and software artifacts belonged of
some CRIS, we can establish a virtual research environment where all free available for harvesting
content's metadata will be visualized like research

Data and Information Space (DIS) and all proposed
tools and services can be connected with DIS objects using some research e
-
infrastructure.

By this way
we get a
reincarnation

of the mentioned above Pan European research portal, but in a more useful form


as a virtual research environment.

Proposed initial tasks:


16.

A model of Pan European research DIS

as a combination of (1)

the content
from the

CERIF
integrated research metadata provided by DRIS Information Hub and (2) the
tools/
services
connected with DI
S content and provided by decentralized developers.

17.

A model of research e
-
infrastructure as
a mechanism to
connect designed tools and services
with the DIS content.

18.

To open a richness of CERIF data within DIS for external information systems (indexing sys
tems,
linking systems, ect.). E.g. using
Schema.org

approach and so on.
