Annual Activity Report
July 1, 2005-June 30, 2006
The
center's mission is to maximize the effective and efficient
use of occupational information by providing specialized occupational tools
(files, reports, software) and technical assistance to users and producers of
occupational information.
The
federal government has funded operation of a national service center for
occupation, industry and training classifications and their relationships to
each other since the early 1980s.
Federal officials realized that collectively they used a variety of
classification systems for their programs, and people outside their agencies
frequently need assistance in obtaining and using those resources
The
National Crosswalk Service Center (NCSC) was established with the State of Iowa
in 1983. The National Occupational
Information Coordinating Committee (NOICC) provided funding. The center’s primary customers were the
federal agencies that constituted NOICC (Departments of Labor, Education,
Defense, Commerce, Agriculture) and NOICC’s network of state committees
(SOICCs). A variety of other customer
types also made use of the center; NCSC products developed for a particular
customer were shared with all.
The
NCSC’s delivery of products and services has changed along with technology, and
the center faces a worldwide market, delivering its products over the
Internet. During much of the 1980s, the
NCSC distributed a few standard files on nine-track magnetic tape for use with
mainframe computers. The center also
produced printed resources extracted from its databases. Increasing availability of personal
computers changed the market for NCSC products and services in the latter half
of the 1980s, with a wider variety of products distributed on diskettes. In 1989, the NCSC began operation of a
dial-up bulletin board system that allowed customers to download files as they
were needed. During this time period,
and increasing share of NCSC resources was devoted to developing customized
products to meet specific needs.
The
Employment and Training Administration of the U.S. Department of Labor assumed
funding for the NCSC in 1997 in anticipation of the end of the NOICC program.
(NOICC stopped operation on June 30, 2000.)
To a large degree, the work and the customers of the NCSC were unchanged
– state Labor Market Information units have always been significant customers,
and their need for classification resources grew as their programs included a
wider variety of information.
This
is the latest in a series of activity reports that document the activities of
the NCSC. Previous reports can be found
on the center’s web site at http://www.xwalkcenter.org/xwrepo.html.
The Employment and
Training Administration provides funding for the National Crosswalk Service
Center in order to meet four objectives:
1)
Work with consortium members to establish a single
point of contact for technical support to assist the states in their
development of the Workforce Information Database.
2) Provide
a conduit for information and data into and out of the Workforce Information
System.
3) Provide
a one-stop resource for classification and crosswalk resources.
4) More fully exploit Internet communication to share files, ideas, feedback, etc. among producers and users of occupational, training and economic information.
The contents of
this report are divided into two major sections. The first section analyzes use of NCSC resources and distribution
of files and other occupational tools.
The second section relates the center’s activities to the work statements
found in its contract with the Analyst Resource Center.
NCSC Utilization
Early
in the center’s operation, staff used the number of requests fulfilled as a
major indicator of use of the center’s services. All contact with customers was direct, whether through the mail
or by telephone, so tracking requests was very straightforward. The addition of the dial-up bulletin board
service in 1989 did not complicate tracking significantly, since the system
generated log files that were easy to analyze.
The
introduction of an Internet server that allowed customers to download files in
late 1997 complicated the tracking of individual requests. Center staff attempted to define customer
requests through analysis of the Internet server logs, but were largely
unsuccessful. The center opted instead
to adopt the count of files downloaded as an alternative indicator of
utilization. The analysis is somewhat
complicated by two log formats produced by the server: one for each protocol
used for downloads – File Transfer Protocol (FTP, at ftp://ftp.xwalkcenter.org) and Hyper Text
Transfer Protocol (HTTP at http://webdata.xwalkcenter.org/ftp/). Center staff import the individual log
files into a database, standardize variable names and formats, and produce file
download estimates that cross both protocols.
(For more information about the NCSC’s analysis of server logs, see
Appendix A.)
The
impact of file availability on the Internet on service delivery is readily
apparent in the graphic below. A
listing of the files with the greatest number of downloads is included as an
appendix to this document.


Other measures of server activity also
reflect the growth in use of this service delivery type:
Note
that server logs were missing for three months of 2001. Analysis of the remaining months’ logs
indicates that the year’s activity was probably roughly on a par with
2000. Note that there are a variety of
events that can have an impact on server activity. The release of a new version of the Workforce Information
Database, major revisions to classifications such as the SOC or CIP, release of
a new set of occupational employment estimates by the Bureau of Labor
Statistics, and the release of new career videos can all have an effect on
server usage.
A
primary group of customers for the NCSC is the group of state database
administrators who populate their versions of the Workforce Information
Database. The center develops
standardized prototype content for many of the database’s lookup and crosswalk
tables as well as providing a variety of national and state data tables. The state-level data tables usually include
data for some substate areas, such as counties, metropolitan areas or cities. The NCSC has analyzed file downloads to
determine the extent to which its customers are utilizing Workforce Information
Database tables and other information.
This analysis includes looks at what portions of total downloads are
made up of Workforce Information Database files; downloads of data files by
geography; and downloads of standardized files for different versions of the
database:

The
portion of total downloads made up of Workforce Information Database files has
increased (up from 47% in 2002-03). The
number of files downloaded for version 2.3 of the database reflects states’
shift to the latest version. Customers downloaded a large number of files for
version 1.1 of the database. For a
count of the number of state-specific files downloaded by state, see Appendix
C.
Some
portion of those downloading files for earlier versions of the database may be
made up of those outside the Workforce Information system – customers whose
applications or other needs are satisfied by the earlier versions’
structures. NCSC files are available
through anonymous downloads to everyone, and customers outside the center’s
primary audience (formerly the NOICC/SOICC network and now the Workforce
Information System) have historically made up about half of the center’s
customers. That’s more difficult to
track when files are downloaded from the Internet, but examinations of
visitors’ top-level domains and types of files downloaded indicate that the
center’s customers are as diverse as the types of files they download. The most common top-level domains are listed
below:

One
would expect that most customers within the Workforce Information System would
visit from .us, .gov or .org domains.
These domain types, when combined with unknown visitors account for only
28 percent of total visitors. The
number of visitors from commercial domains, as well as the number of foreign
countries from which others visit reflects the diversity of the center’s
customers. For a complete listing of
the countries of the server’s visitors, see Appendix D.
Another
reflection of the center’s customers’ varied interests in occupational
resources is the type of files downloaded.
Visitors can choose from over 6,000 files for downloading. Of those, slightly over 57 percent are
formatted for use in the Workforce Information Database. Those files accounted for over 60% of the
files downloaded. Career videos and
O*NET files also had significant numbers of downloads. The NCSC has distributed O*NET files since
the classification was established in the late 1990s. They have among the center’s most popular products year after
year.

The
anonymous nature of Internet file transfers makes identification of individual
customers quite imprecise. However, the
NCSC tracks e-mail contact with customers.
Customers who contact the center using e-mail. These customers frequently have questions about the contents and
uses of NCSC files and other resources or are searching for resources that
might not be readily identifiable. The
list of e-mail contacts also reflects the diversity of the center’s customers:

Work Statement
Activities
The major activities of the NCSC are defined in the work statement
document that is part of the contract for operation of the center. The contents of the work statements are, to
a degree, shaped by the Employment and Training Administration’s goals for the
center. One of those goals is the
movement of information into and out of the Workforce Information System. The diversity of the subject matter
downloaded and the customer information described in the previous section
indicate a broad interest in the classification, crosswalk and data resources
offered by the NCSC indicate that this goal is being met. Specific activity related to individual work
statement items is described in this section.

Appendix A
Analysis of NCSC Internet
Server Log Files
The
examination of the delivery of products and services by the National Crosswalk
Service Center in this report relies heavily on the analysis of log files from
the center’s Internet server. That
server’s main function is the distribution of files through the Internet File
Transfer Protocol (FTP). Files are also
downloaded through the World Wide Web Protocol, HTTP. The NCSC’s home page is located on a separate server, operated by
the State of Iowa, and use of that web site is not included in the analysis.
Two
types of analysis are included: measures of overall server activity, and the
characteristics and number of files downloaded by customers. The procedures in producing both types of
data are described briefly below:
o
Measures of
overall server activity: Aggregate measures of server use (hits,
bandwidth, characteristics of visitors) are developed through the use of WebLog
Expert software (www.weblogexpert.com). This software analyzes the content of the
123 MB of server log files and develops a variety of measures. A number of these measures, type of
top-level domain, most active organizations and country of visitors reflect the
wide variety of users who visit the center’s server.
o
Characteristics
and number of files downloaded:
This analysis includes a variety of dimensions including counts of files
downloaded, geography and versions of Workforce Information Database files
downloaded, and others. During this
analysis, log files are imported into a database, files read by Internet search
engines are excluded, activity by NCSC staff is excluded, and counts of files
viewed/downloaded are generated. In
order to generate those counts, information about the locations of files
downloaded must be standardized. Files
downloaded via the FTP and HTTP protocols display different file locations,
despite being the same files. After
those differences are removed, download counts for individual files can be
generated.
