[legalxml-intercept] revised project list

[Tony Rutkowski <trutkowski@verisign.com>]

Hi all,

Many thanks for participating in the first LI-XML
teleconference today.  It seemed not only quite
useful, but an effective means of international
cooperation.

The suggestions regarding additional or clarified
project descriptions are included in the revised
attachment.

As we discussed, it would be greatly appreciated
if each of you could annotate these projects with
your views as to importance and immediacy, and
privately send the information to me.

I'll compile responses into a new revision that
will constitute the consensus on deliverables in
the LI-XML charter.

cheers,
tony
OASIS LI-XML Projects                        v1.2 6 Jan 2003

Global LI Framework schema
 
The Framework is the principal initial core activity of 
the LI-XML TC.  It consists of two parts - a global
framework, and a set of individual modules.  Each module 
has a designated scope that includes global, regional 
(i.e., groups of countries), national, agency, state/
province, or municipal variations.


1.0   LI Global Framework 

    The Global Framework is the generalized model capable
    of encompassing all Lawful Intercept activities
    worldwide, including initial information discovery,
    review of communication records, authentication, and 
    interception and delivery of communications signalling 
    or content, including associated judicial or 
    administrative orders.

1.1 LI global object dictionary

    At present there are several dozen different LI
    handover standards, each with dozens of different
    object identifiers - many for the same objects. 
    Layered on top of this ensemble are a significant
    number of new object identifiers that will be developed
    as part of the LI-XML project or borrowed from other
    LegalXML projects.  This will include many national and
    local variations.  Building and maintaining a LI Global
    Object Dictionary is key part of this activity.  This
    necessarily includes the creation of a global LI Law 
    compilation.
    
1.2 Global LI Tag & bag meta schema
 
    Increasingly large amounts of Intercept Related
    Information and Content are being cached or archived
    today.  Doing so will be increasingly critical in doing
    signature analysis to discover technically agile
    criminals and terrorists.  However, in much of the
    Lawful Interception environment, IRI and CC are
    captured and analyzed only as source information - in
    each instance using one of the multiple insular
    standards-based or proprietary specifications.  The
    need for a common meta information schema for tagging
    this information is well appreciated within the "next
    generation" LI community.  This working group will
    focus primarily on XML tagging of network user
    information or intercept data and content; combined
    with an associated "bagging" schema for global storage
    and analysis.
    

    LI Framework modules (tentative)
    --------------------------------
2.1 Initial information discovery

    The most common and numerically frequent LI related
    activity is the simple act of looking up basic
    information about a communications identifier (such as
    a phone number or email account), or determining all
    such identifiers of a suspect.  However, there is no
    effective means for doing this in an authoritative,
    electronic fashion except for a few proprietary national
    implementations.  The objective is to  develop a 
    Global User Identifier Lookup schema.

2.2 Review of communication records

    The second most common and numerically frequent LI
    related activity consists of requesting the records of
    a specific user from a communication services operator. 
    There are no means of doing this electronically.  The
    objective is to develop a Global Communications Record
    Lookup schema.

2.3 Interception and delivery of communications signalling or content

    Several dozen diverse international, national, and
    industry sector standards organizations have produced
    (or are producing) ASN.1 specifications for Handover
    Interface ports for the interception and delivery of
    communications signalling or content. No administrative
    schema (HI1) exist; and many if not most of the H12
    (signalling) and HI3 (content) identifiers are
    non-interoperable, and a plethora of disparate
    protocols exist.  The objective is to identify and
    provide a means of discovering on a continuing basis,
    all LI related XML schemas and ASN.1 modules, translate
    those modules into authoritative, interoperable XML schema,
    and develop needed HI1 (administrative) XML schema.

2.4 Judicial or administrative orders

    Many LI related activities require application to be
    make by a Law Enforcement Agency to judicial or
    administrative authorities to obtain a warrant, order,
    or subpoena.  This is a specialized subset of the
    activity being dealt with by the LegalXML Electronic
    Court Filing TC, that will be done in liaison with
    them.  The objective is to develop specifications 
    for the use of XML to create LI related documents and to
    transmit those documents from an Law Enforcement Agency
    to a court or LI administrative body, from the court or
    administrative body to a communications provider or
    agent, or to another court, and includes the handling
    of highly classified court documents.

2.5 Authentication and verification schema
 
    Many tens of thousands of parties are involved globally
    in Lawful Interception process, involving an even
    larger number of communications technical facilities. 
    This includes Law Enforcement Agencies, Law Enforcement
    Monitoring Facilities, Communications Services
    Providers and Agent Mediators, and Network Elements. 
    Yet there is no global mechanism by which these parties
    and facilities are even known, much less capable of
    verification or authentication.  The needs are similar
    to other OASIS TCs dealing with registries and
    authentication.  The objectives are to develop
    specifications for interoperable LI Global Identifier
    Registries and associated verification and
    authentication schema.

2.6 Reporting schema

    Many different nations and local jurisdictions have
    transparency reporting requirements for LI meta
    information.  Typically this takes the form of the
    number of Intercept Related or Call Content orders
    effected pursuant to provisions of organic law.  The
    objective is to develop common global specifications
    for the creation and exchange of this derivative
    information.
