I have a .bib file with references, and a .org file with annotations. Like:

.bib file:

@book{Saul.2013.DoctorYourselfNaturalHealing,
  title = {Doctor yourself: natural healing that works},
  shorttitle = {Doctor yourself},
  author = {Saul, Andrew W},
  year = {2013},
  publisher = {Basic Health Publications},
  address = {Laguna Beach, CA},
  isbn = {978-1-59120-310-0},
  language = {English},
  annotation = {OCLC: 883386139}
}

.org file:

*** Saul, A. W. (2012) "Vitamin D"
Supplements represent an efficient way to obtain sufficient vitamin D. African-Americans should consider taking 3,000 international units (IU) per day while White Americans should consider taking 2,000 IU/day. The current dietary guideline, approximately 400 IU/day, was based on the amount of vitamin D in a spoonful of cod liver oil, which prevented rickets.

There are few adverse effects of vitamin D. With whole-body exposure to the sun, one can make at least 10,000 IU/day in a short time. _Adverse effects such as hypercalcemia have been found in general only for 20,000–40,000 IU/day for very long periods._ However, those with certain diseases such as adenoma of the parathyroid gland, granulomatous diseases, lymphoma, sarcoidosis, and tuberculosis, should limit their vitamin D intake or production due to the fact that the body’s innate immune system produces too much 1,25-dihydroxyvitamin D in the serum, which can raise serum calcium levels too high.

Could I write on the .bib file using the orgmode power? Something like this could work as a .bib file, or is it a no-no?
