Is LinkedCT's data Open?
Refer to this page for more details.
How up-to-date is the data?
A script is always running in the background to keep the data fresh. However, this doesn't mean that the data is up-to-date at all times. There might be a delay until our system gets notified about new trials or changes in the old trials. This delay might be a few seconds or a few days (or even weeks). On average, it will take less than a day for the new trials to show up, but the update process might be slower simply because it takes longer to identify a change, but we can instantly find out if there are new trials made available on ClinicalTrials.gov.
What happened to the (old) static LinkedCT?
Can I download all the data?
You can only download static data dumps made available here. We will do our best to have a new dump every three months.
I have been issuing a lot of queries to LinkedCT's server, but now I cannot access the server anymore. What is wrong?
We have a small server hosting a large amount of data. We expect the users to issue queries responsibly, otherwise we unfortunately have to block their IP addresses. If you think we have blocked your IP address by mistake, send us an email and we will fix it. Please have in mind that the project is still in its preview phase and we might have short, temporary down times. Contact us only if the data is not accessible for a long period of time (say a few hours).
If you really need the live databrowse interface and SPARQL endpoint for regular use and possibly expensive queries, and you can afford to pay for a virtual server, drop us an email and we might be able to set up a custom more powerful server for you.
