The OCHEM database supports access to the data for guest and registered = users. Registration is free and open for everyone. We strongly encourage re= gistration since only registered users have access to the full set of featu= res. The OCHEM database is based on the Wiki principle: all users can intro= duce new experimental data and modify the data introduced by others, with t= he particular access restrictions discussed below.
There are different access levels for users, summarized in the figure be= low: guest (anonymous) users, normal users, privileged users and administra= tors. By default, a new registered user has a =E2=80=9Cnormal=E2=80=9D acce= ss level and can be elevated to =E2=80=9Cprivileged=E2=80=9D by the system = administrator. Users can modify data introduced by other users from the sam= e or lower access level group. For example, privileged users can modify dat= a introduced by other privileged users, as well as by normal and guest user= s. Guest users have the lowest privileges and a limited functionality, e.g.= , they cannot store and modify models. For every entry OCHEM stores and dis= plays the original depositor and the last modifier of the record, with time= stamps of record creation and last modification. Additionally, the OCHEM st= ores all record changes with a reference to the date of change and the user= who modified the record. Thus, all the changes are traceable and, if neces= sary, can be manually reverted to the previous state.
An overview of different user levels in the OCHEM. User=E2=80=99s rights= decrease with level. Users can edit/delete entities of the same or lower u= ser levels
Currently there are three main group of Users:
The users are automatically validated by the Administrator (usually duri= ng 1-2 days after the registration) if they register with their insti= tutional or company account and properly fill in the field= s in the registration form. If a User does not have such account as, e.g. a= s a student, he/she should write to ochem@vcclab.org to explain it.= p>
By default, all records introduced to the database are publicly availabl= e unless the user explicitly makes the records private. All the access rule= s discussed above apply to the public data. Private records can be viewed a= nd modified only by the introducer or by members of the same group.
The administrator can combine users in groups. The members of the same g= roup can view and edit private records as well as access models and baskets= of each other. This allows a group to work on the same project without mak= ing their data and models public.
The registration is open for everybody and requires a user to fill out a= standard registration form with obligatory specification of login, passwor= d and email address. Immediately after registration, the user can access hi= s account and use the OCHEM.
Users receive bonus points for registration (100), validation of their a= ccount, i.e. privileged users (1000), publishing of moderated records on th= e OCHEM (depends on the property weight, normally 1 bonus point per one rec= ord) as well as they can collect properties as Moderators.
N.B.! No bonus points are given for hidden or non-validated records to a= void spamming of OCHEM with noise data.
The users who contributed any public data to OCHEM will be allowed to do= wnload the data of other users (e.g., in Excel or SDF format). The number o= f records that can be downloaded by a user will be proportional to the numb= er of new data records that (s)he uploaded and were validated by the admini= strator. We expect that this feature will motivate users to upload new data= and to make these data public to the community. This feature is currently = under development.
