according to uniform rules for all sciences. In other 
words, the CDSSK consists of a set of subspaces 
related to individual areas of science interconnected 
on the basis of an unified ontology to the whole space 
(Antopol'skij  et  al.,  2019
).  This  unified  ontology 
includes a number of subject ontologies that describe 
individual scientific areas with the help of thesauruses 
and classification systems. 
Each  subspace  of  the  CDSSK  includes  axioms 
and  fundamental results that form  the  basis  of  each 
specific  research  area,  as  well  as  a  dynamic  part 
containing information on cutting edge science in this 
field. 
For  each  separate  field  of  science,  specific 
scientific  knowledge  is  defined  for  each  individual 
field of science. There are two classes of knowledge 
in almost all areas of knowledge: a priori knowledge 
and  experimental knowledge  (Antopol'skij  et  al., 
2019). 
The DIS resources are a source of the CDSSK 
content.  These  resources  should  be  analyzed  for 
reliability, importance and relevance. 
Scientific  social  networks  provide  numerous 
services  for  share  information,  posting  research 
results, reviews and comments, search for vacancies, 
etc. (Kalenov et al., 2012). 
The  formation  of  the  CDSSK  involves  the 
development  of  special  approaches  and  algorithms 
that are based on new principles. 
2  STRUCTURE OF THE 
COMMON DIGITAL SPACE OF 
SCIENTIFIC KNOWLEDGE 
The space of scientific knowledge should include two 
components  -  static  and  dynamic.  The  static 
component  is  the  fundamental  theoretical  and 
experimental  data  tested  by  time  and  practice.  The 
dynamic component  is  a  part  of  the  CDSSK  which 
includes new data and knowledge. 
These components can be considered as two parts 
of  the  knowledge  space.  One  of  which  -  basis  - 
contains fixed scientific  knowledge, and the other - 
suspension - new scientific information. At the same 
time, after passing through an expert filter, the second 
part goes into the first (Sobolevskaya and Sotnikov, 
2019). 
The  connections  between  the  basis  and  the 
suspension  can  be  managed  at  the  level  of  an 
interdisciplinary  scientific  ontology.  At  the  same 
time,  the  basis  and  the  suspension  are  a  class  of 
subspaces (facets) in various scientific fields. 
3  CONTENT OF THE COMMON 
DIGITAL SPACE OF 
SCIENTIFIC KNOWLEDGE 
Information  resources  are  the  sources  of  scientific 
knowledge.  They  contain  postulates,  theories, 
experiments description, experimental results and are 
presented on physical storage media (Kalenov, 2014).  
As  a  rule,  the  information  contained  in  these 
resources  is  reliable  and  verified  (Chen  and  Lu, 
2015). However, an expert examination is required to 
decide what is to be loaded to the  CDSSK. Experts 
should  be  qualified  representatives  of  the  scientific 
community in the relevant subspace area. 
The  basis  and  superstructure  of  the  CDSSK 
consist  of  a  kernel and a convex shell  (Kalenov, 
Sobolevskaya, Sotnikov, 2019). 
Digitized publications, archival materials, images 
of  museum  exhibits,  multimedia  materials,  and 
thematic  databases  supported  by  scientific 
organizations form the convex shell of the CDSSK. 
4  SHAPING CONTENT OF THE 
COMMON DIGITAL SPACE OF 
SCIENTIFIC KNOWLEDGE 
The CDSSK is based on the principle of distributed 
data  with  centralized  editorial  processing,  content 
downloading and technology support. 
The digital library "Scientific Heritage of Russia" 
(DL  SHR)  (http://e-heritage.1gb.ru/Catalog/IndexL) 
has been operating since 2010. The DL SHR is based 
on  the principle  of  distributed  data  with centralized 
editorial  processing,  content  downloading  and 
technology support (Sotnikov et al., 2017). More than 
20  libraries,  institutes  and  museums  prepare 
information for DL SHR according to uniform rules. 
Object-oriented  design,  data  distributed 
technology, various digital scientific objects as well 
as  the  long-standing  positive  experience  in  the 
operating of  the  DL  SHR allow  us  to consider  as  a 
prototype of the Common Digital Space of Scientific 
Knowledge (CDSSK) (Antopol'skij et al., 2019.). 
In  accordance  with  the  DL  SHR  metadata 
standards  bibliographical  data  related  to  scientists, 
their scientific interests in terms of classification, and 
a bibliography of  their  main works are  entered into 
the library. 
Librarians perform this work. It includes 3 stages: 
- the  search  for  sources of scientist  biographical 
data and the compilation of a detailed biography;
