In a couple of email exchanges this weekend the “Right to Use” FAQ regarding data provided on ChemSpider was under discussion. The FAQ page hasn’t been updated since we went live in March so, based on almost 6 months of experience with feedback and commentary, and stimulated by the exchange over the weekend I’ve updated the statement on the FAQ page to state the following:
“May I download the data and use it in my own database(s)?
You have limited rights in this regard. You can only assemble a database of 5000 structures or less, and their associated properties, from our database without our permission. You can download up to 1000 structures per day from the website. Please contact us at feedbackATchemspiderDOTcom to request an extension outside this constraint. We are willing to provide the ENTIRE database of ChemSpider structures at your request – the file will consist of InChI Strings, InChIKeys and ChemSpider IDs. These constraints are under regular review so please feel free to engage us in conversation.”
What we’re trying to do here is to stop the offshore raiding of the database that is going on. Certain groups are attempting to download the database and putting an incredible load on our server(s). So, please stop!
We are presently in the process of downloading the entire database into a series of SDF files so that we can provide the ENTIRE ChemSpider database to interested parties. We will cross the 20 million mark shortly in terms of unique structures on the database. Each structure will be accompanied by the InChI String, the InChIKey and the associated ChemSpider ID. We are INTENT on proliferating the value of InChI across the chemical community and expanding the value of InChI to the semantic web.
So, a question to you, our readers…is there anyone out there who would like to receive the ChemSpider database when it is ready? Please let me know by responding to this blog post. Thanks
