> In response to your queries regarding cessation of the RIN service
> which you recently posted to the PIUG, we would like to address
your
> concerns and also take this opportunity to clarify some of the
points
> which you have raised.
>
> Firstly, as you are aware, Derwent defines a Ring Index
> Number (RIN) as a code applied to a chemical ring system which
does
> not have a specific chemical fragmentation code, and this
therefore
> allows more precise searching of chemical ring systems. The RIN
> Service provides an update of all the new RINs generated by
Derwent
> Indexers as they encounter them for the first time in patent
> documents.
>
> The RIN Service is now subscribed to by only a relatively small
number
> of customers (approximately 20), and only a very small number of
new
> RINs are currently being generated by our Indexers each week. In
> addition to this the same information covered by RINs already
forms
> part of DWPIM (MMS), and will also be duplicated as a part of the
> proposed DCR indexing for DWPI. Consequently, it seems clear that
the
> requirement for the generation of new RINs is diminishing.
>
> Therefore, it was decided that the RIN Service should cease in
> January 1999, when Derwent's indexing teams process the final 1998
> data (in Derwent week 9851). All existing RIN Service customers
will
> get the final instalment of RIN data files once they are processed
in
> the next few weeks.
>
> However, as you suggest, there is still a need for our Indexers
> (Analysts) to continue to apply existing RINs (particularly for
users
> of Markush TOPFRAG), and this is fully appreciated by Derwent. We
> would like to reassure you that all existing RINs will continue to
be
> used by our Indexing staff.
>
> An updated version of Markush TOPFRAG was expected to be launched
> towards the end of last year, and it had been our intention to
combine
> that announcement with that of the discontinuation of the RIN
Service
> (as we believed this approach would be the best way to inform all
> interested parties). However, the new version of Markush TOPFRAG
has
> been slightly delayed, so the joint announcement has not yet been
sent
> out. Unfortunately we did not fully appreciate within Derwent
that
> this would also delay notification of the RIN Service
developments.
>
> We can only apologise for this oversight.
>
> Derwent has invested a lot of time and effort to ensure that
Chemical
> Indexing (BCE Chemical Fragmentation Coding) continues to be
applied
> alongside DCR indexing. We are committed to the concept of
Chemical
> Indexing as a retrieval mechanism for customers (as we have
> demonstrated in the past), and will continue to develop and apply
it
> alongside our other forms of indexing, until such time as our
> customers request otherwise.

> We hope this information answers your queries and allays any fears
you

>
> Please feel free to post any information contained within this
reply

other
> PIUG members. In the meantime, we will work speedily to send out
a
> formal notice to this effect to everyone affected.
