Versions

The Neuropterida Species of the World (NSW) is an integrating resource that contains web site and database elements. Both classes of elements are updated episodically. Significant one-time or cumulative updates are sequentially numbered as new ‘versions.’ Smaller updates – to data, functionality, or both – made between version breaks are treated as ‘releases.’ In the tables below, the states of the NSW on the dates of initial release of several of the versions, and sometimes the active release, are provided for a variety of documentary data. Table 4 provides information on release dates and selected benchmark metrics and highlights; table 5 gives counts for several classes of data of nomenclatural and taxonomic interest; table 6 presents publication usage data (cumulative page accesses) for several NSW pages; table 7 summarizes design and functionality changes; table 8 displays links to an archive of “snapshots” of selected NSW pages; and table 9 provides data on the size and scope (record and column counts) of the primary data tables used to deliver the NSW.

Table Key: Show. Abbreviations: "–" – not available; n/a – not applicable (no such page). Columns: Catalogue Record Pages – the number of distinct Catalogue Record pages programmatically generated in the version or active release; the number of Catalogue Record pages is approximately equal to the sum of the number of unique available and unavailable names treated at each rank in the extended species group of ranks (i.e., species, subspecies, infrasubspecies, subinfrasubspecies); Highlights – notable features or milestones associated with the version or active release; Monograph Record Pages – the number of distinct Monograph Record pages programmatically generated in the version or active release; the number of Monograph Record pages is approximately equal to the number of valid Neuropterida species and subspecies plus the number of unavailable Neuropterida species-group names that are not assigned to a valid species or subspecies; Searchable Combinations – the number of distinct scientific name combinations (i.e., unique searchable strings of available and unavailable genus- and species-group names) contained in the version or active release; Release Date – the initial release date of the version or active release; Version – the number assigned to the version or active release.

Interval	Changes

Version 6.0 to Version 7.0	–
Version 5.0 to Version 6.0	General: Implemented new icons for links to digital literature files and to Bibliographic Record pages of the LDL Bibliography of the Neuropterida. Search Results Page: Implemented access to a new suite of pages, the Monograph Record pages, through the establishment of new links placed on scientific names displayed in the Current Name column. Monograph Record Page: Added a new set (ca. 7600) of interactive data synthesis pages -- the Monograph Record pages. Each Monographic Record page aggregates the Neuropterida Species of the World data that is available for a particular valid species or subspecies. The initial data blocks included on the Monograph Record page were: Taxonomic Status, Scientific Names [Short Form, Long Form, Original Combination (species), Original Combination (subspecies), Nomenclatural Gender Forms (species), Nomenclatural Gender Forms (subspecies)], Synonyms [with combo box option: Show All Synonyms, Hide Synonyms, Show Original Combination Synonyms Only, Show Synonymw with Available Names Only, Show Synonyms with Unavailable Names Only], Figures [with Hide Figures Table link and Show\|Hide Table Key], Keys [with 'Show a list of Keys' link], Geographic Distribution [Summary Statement, Notes, Countries\|Country Records (with combo box options: Show Countries (no duplicates or sources), Show Country Records (with duplicates and sources), Hide List)], Lithostratigraphic Distribution [Summary Statement], Temporal Distribution [Extant/Extinct, Temporal Range], Primary Type(s) [Kind / Sex / Repository, Type Locality (quote), Type Locality (interpreted and standardized), Age, Stratum], Dataset Timestamps [tblLdlSpCat]. References: Added icon-based Bibliography of the Neuropterida, Bibliographic Record page links to the references table; updated Table Key. Citation Page: Removed page; moved all citation data to the Main page. Versions Page: Divided the "summary and comparative data" table into two separate tables: "version dates, benchmark metrics, and highlights" and "species-group names and valid taxa". Added a new Monograph Record Pages column to the "version dates, benchmark metrics, and highlights" table to enable tracking of future growth of the Monograph Record page suite. Added five new columns (Non-Neuropterida, Valid Extant Species, Valid Extant Subspecies, Valid Extinct Species, Valid Extinct Subspecies) to the "species-group names and valid taxa" table to expanded tracking of comparative taxonomic and nomenclatural data. Divided the "usage data and page archive" table into two separate tables: "usage statistics" and "page archive". Added four new columns (Introduction, Catalogue Record, Monograph Record, and Versions) to the new "usage statistics" table to enable tracking of usage on additional pages; removed the Classification column from the same table (in anticipation of moving classification display functionality to a more flexible format in a new LDL module). Added one new page (Monograph Record) to the new "page archive" table. Added a new table ("principal data tables") to document size and scope of the primary datasets that support the NSW module. Bottom Navigation Bar: Removed Citation page link.
Version 4.0 to Version 5.0	Main Page: Modified to directly display author contact information and publication citation data; Introduction button added. Introduction Page: Table formats updated to LDL standard; higher classification table moved to new Classification page. Classification Page (new): Static higher classification table formerly located on Introduction page moved to new Classification page and table dynamically linked to dataset of active release; table data extended to display information on whether each higher taxon contains Holocene and/or pre-Holocene taxa. Simple and Advanced Search Pages: Added functionality to search for species-group and subinfrasubspecific ranked name epithets. Search Results Page: Improved display of search parameters on Search Criteria line; improved readability of Search Results table by removing subgeneric name epithets to a separate column; added Current Name field to Search Results table; removed Combination field from Search Results table; added functionality to display species-group and subinfrasubspecific ranked names to Search Results table. Contacts Page: Removed page; moved contacts data to the Main page. Versions Page: Redesigned and reimplemented page; table formats updated to LDL standard; implemented '(active release)' line in Tables 4 and 5 to allow tracking of selected data parameters between formal versions. Log In Page (new): Added Log in functionality to NSW module. Bottom Navigation Bar: Added new Log In page link; removed Contacts page link.
Version 3.0 to Version 4.0	General: Complete backend code rewrite for the Neuropterida Species of the World module.
