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.


Curation Rules

Curation Permission
  • To ensure content reliability, only registered users are allowed to edit/curate the database information.
  • 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.
Database Meta-Information
  • 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 users.
  • For dead databases, their meta-information are obtained and extracted from their related publications.
  • 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, input "NA".
  • There are a total of 13 database categories. A database may encompass multiple database categories.
  • 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 organisms.
  • Species list is obtained from NCBI Taxonomy database and some species may not be included in the present list.
  • 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 the database.
  • 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.
Database Citation & Age
  • 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".
