message: Do the numbers in the "Virus Family" column of the DNA Viruses and RNA Viruses tables mean anything, or are they just kind of there? (E.g. is Parvoviridae always DNA virus family number 3, by some authoritative source?) I'd suggest removing them if they're not meaningful, or explaining and citing a source if they are meaningful. -Agyle 03:22, 20 September 2007 (UTC)
thread_title: Virus family numbers?

message: The abbreviation ICVCN (with piped link to this article) appears in the article Biology in the paragraph shown below, but does not appear here in this article.
:The dominant classification system is called Linnaean taxonomy, which includes ranks and binomial nomenclature. How organisms are named is governed by international agreements such as the International Code of Botanical Nomenclature (ICBN), the International Code of Zoological Nomenclature (ICZN), and the International Code of Nomenclature of Bacteria (ICNB). A fourth Draft BioCode was published in 1997 in an attempt to standardize naming in these three areas, but it has yet to be formally adopted. The Virus International Code of Virus Classification and Nomenclature (ICVCN) remains outside the BioCode.
Could this please be added in proper context so that people redirected here will find some material in context to satisfy them. AshLin 04:29, 28 September 2007 (UTC)
replies: text: I am fairly sure ICVCN refers to the ICTV's classification system, although I can't find a good, clearcut reliable statement relating the two. It seems like the code is informally referred to as "the ICTV code," "the ICTV database," and is formally cited as "The Seventh Report of the ICTV" or something, and that ICVCN is used rarely (perhaps more commonly around 1998-2000). Examples of dual usage this abstract, and this website. I'm hesitant to add info to either article clarifying this without an unambiguous citation. -Agyle 18:29, 28 September 2007 (UTC)

text: (@ Agyle) For a "good, clearcut reliable statement relating the ICVCN and ICTV taxonomy" see the paragraph 8.1 of the ICTV Statutes. Another relation: The Comment to the paragraph 1.2 of ICVCN refers to the Master Species List, which is also basis for the current ICTV Taxonomy. (ICVCN incl. the binomial nomenclature for the virus species is strictly applied for new taxon names.) --Petr Karel (talk) 09:31, 8 January 2024 (UTC)
replies: text: Since the Code is now called "The International Code of Virus Classification and Nomenclature (ICVCN), March 2021 edition" on its own website and as now cited in the article, I believe that satisfies the requirement to explain the acronym :) Tony 1212 (talk) 17:06, 8 January 2024 (UTC)
thread_title: Abbreviation ICVCN

message: It appears that the table under the RNA viruses heading is meant to list RNA viruses, but the Retroviridae are considered group VI in the Baltimore classification (whereas only groups III, IV, and V are listed as strictly RNA viruses here on this page).  Should the Retroviridae be removed from the RNA virus table?  Should the table include the Baltimore classifications?Scray (talk) 04:53, 11 April 2008 (UTC)
replies: text: Here's a relevant link to ICTV that shows the reverse-transcribing viruses clearly distinct from the RNA virusesScray (talk) 11:11, 11 April 2008 (UTC)

text: I checked out Scray's edit when it was made. He appears to be correct - see See Also link at bottom of page. In Baltimore's classification retroviruses belong to Group VI, and therefore don't belong in a list of taxa in Groups III-V. Lavateraguy (talk) 15:44, 11 April 2008 (UTC)

thread_title: Positive/negative sense?

message: What is the basis for the 'virus family' classification in the table in this section? 
There are seven 'families' which is confusing since they echo the seven groups under Baltimore. At least it's confusing to me as a non-taxonomist... For instance it sort of suggests the Hepadnaviridae/HBV ('family 6') are in Group VI. ICTV isn't very helpful (Hepadnaviridae are an unassigned family) but i've not come across this system before so i'd like to know more about it (although it seems coherent enough.) If it's just a listing of recognised families, would it be helpful to list their baltimore groups s well, to make it clear where they fit in the overall ICTV scheme? ditto the equivalent table under RNA viruses section.
Can anyone enlighten me / give a reference for this system? I don't have Virus Taxonomy to hand... Cheers...

thread_title:  DNA viruses - summary table 

message: The tables in the "Baltimore Classification" system appear to be from a different taxonomy. I was very confused when I found the "Hepatitis B" entry in what appeared to be the "Group II" table.
I attempted to unscrew this mess by adding a column to each table giving the Baltimore group, but if the tables are in fact from some othre taxonomy, they should be removed fromt h eBaltimore section and added to a new "comparison of classificatins" section. -Arch dude (talk) 13:52, 9 September 2008 (UTC)

Wouldn't it be better to say:

replies: text: But it never said they were viruses, but rather "Subviral agents", ie. beneath the complexity of viruses. If you read the ICTV 9th Report (2011) Subviral Agents (2011) it does list prions as being subviral agents. --Jules (Mrjulesd) 22:07, 4 January 2021 (UTC)

message: So, how are viruses classified in the sense of organizing them into the ICTV hierarchy (realm, kingdom, phylum, and so on)?  The article appears to say nothing at all on this subject.  The Baltimore system is separate, and the LHT system appears to be an alternate system.  — Preceding unsigned comment added by 2603:9000:AC08:A600:F9A2:D64C:B3D4:6FBF (talk) 00:36, 10 June 2020 (UTC)
