Curation Rules, Usage
Policies and Disclaimers
All information in Database Commons are updated from time
to time, with possible changes on curation rules,
usage policies and disclaimers wholly or partly at any time and without giving notice. The date of the most
recent revision will appear on bottom of this page. If you do not agree to the following items, please do
not continue to use our online services.
- To ensure content reliability, only registered users are allowed to edit/curate the database
- Registered users can apply for curation permission by email. The Database Commons Team will review the
applicants' qualification but does not guarantee the application will be approved.
- The Database Commons Team performs curation from time to time, and also encourages database
developers/curators/team-members to curate their own databases.
- Database Commons reserves the right to stop, to limit or to terminate your curation permission for any
inappropriate or disruptive behavior on our website or revelant webpages.
- If you post or send offensive, inappropriate or objectionable content anywhere on or to our websites or
otherwise engage in any disruptive behavior on any of our services, we may use your personal information
from our security logs to stop such behavior and terminate your account. Where we reasonably believe
that you are or may be in breach of any applicable laws we may use your personal information to inform
relevant third parties about the content and your behavior.
- In terms of accessibility, databases can be classified into alive and dead, where the former are
available, whereas the latter are unavailable temporarily or permanently due to various reasons.
- Database Commons collects not only active databases but also dead ones, just considering that all
related meta-information of dead databases can also provide important history and insights for
- For dead databases, their meta-information are obtained and extracted from their related
- The "Year Founded" indicates which year the database was founded. Albeit debatably, Database Commons
considers the year of its first publication as "Year Founded".
- Many databases provide the last update information in the homepage and thus "Last Updated" was
curated based on this.
- URL is automatically obtained from publication and further manually curated by curators. This URL
should direct users to the database homepage rather than other pages. If the URL has changed during
update, it should be changed to the newest one.
- The "Accessibility" includes two options, namely, "Accessible", "Unaccessible", which are manually
curated and checked by curators
- The "Description" is summarized by curators based on publication abstracts, which often should be
concise and clear (1-3 sentences).
- Controlled vocabularies are used for three meta-information items, viz., "Data Type", "Data Object",
and "Database Category".
- Three data types include "DNA", "RNA", and "Protein". A database may encompass multiple data types.
If these three data types are not appliable, please select "Other".
- There are a total of 6 data objects, viz., "Animal", "Plant", "Fungi", "Bacteria", "Archaea", and
"Virus". A database may encompass multiple data objects. If no species information is available,
- There are a total of 13 database categories. A database may encompass multiple database
- For "Species", Latin names of the organisms are required and should be selected from the drop-down
box. If the database covers quite a large number of organisms, users could input names of the major
- Species list is obtained from NCBI Taxonomy database and some species may not be included in the
- Keywords are tagged to show the important features of databases. The singular form is preferred
rather than the plural form. All letters should be in lowercase.
- The contact information is provided to facilitate the update of database information, and it is
curated based on the contact details in the database or the related publications. To ensure
effective contact with database owners/developers, we give priority to the contact details shown in
- For "University/Institution", official English full name of the university/institution is required.
If the university has multiple campuses, the campus's name should be included, e.g., University of
California Santa Cruz. If institutions are affiliated to an academy, the academy's name should be
listed, e.g., Beijing Institute of Genomics, Chinese Academy of Sciences.
- The "Citation" indicates the total citation count for a specific database, based on the summed
citations (indexed by Europe PMC) over all its related publications.
- Database age is calculated since the year of its first publication.
- z-index is calculated by dividing citation by database age, and this index is conductive to reducing
influence of database age and enables relatively fair comparison between newly constructed databases
and old well-established databases.
- Databases are ranked by z-index. Rank numbers among all databases and among specific database
category/categories are listed in the database page.
- For any given database, its related databases are classified into "Cited" and "Citing", where
"Cited" represents databases that cite this database, while "Citing" represents databases that have
been cited by this database.
- Curation events are recorded by day. Curators may curate a specific database for many times per day,
but this would be registered as one record in "Record metadata".
- Database Commons does not warrant or assume any legal liability or responsibility for the
correctness, accuracy, up-to-dateness, completeness, reliability or usefulness of any published
- Database Commons does not endorse or recommend any resource, product, process, or service. The views

publish the contents wholly or partly at any time and without giving notice.
