GoBioSpace' depositors

GoBioSpace is a tool to turn measured masses into source tagged sum-formulas and with this blog entry I want to focus on the datasources.

In contrast to combinatorial sum formula prediction tools coming up with a blank formula, the GoBioSpace user gets a formula tagged with many more information such as names, InChIs, hyperlinks and so on. To make this clear GoBioSpace heavily depends on its data sources, and PubChem (Compound and Substance) and ChemSpider are the biggest ones. First, I want to thank those data sources for making the data available to the community and I want to thank for the time and effort the people spend in developing this databases. Second, I want to give a short statistic with respect to the data sources. The table given below lists all databases sourced into GoBioSpace showing the total number of sum formula coming from this database and the number of sum-formula which are made available only from this depositor (no other depositor published this formula).

PubChem was imported at 2011-FEB-15th. PubChem refers to PubChem Compound where as PubChem (...) refers to PubChem Substance with the specific sub database
One striking observation is that ChemSpider has in the later import 2011 a large proportion of unique formula,which are not included in the import from 2008. In fact, many of those formula are tagged as "This record is deprecated and may be removed soon." on the ChemSpider website.What does this mean for the chemical formula? Is the formula valid?

Some other observation from the import of the Yeast Metabolome Database is, that also smaller databases contribute formula which are not included so far in the larger databases PubChem and ChemSpider.

Any thoughts?
