It gives C++ developers libraries, headers, sample utilities, and a ZOOM C++ binding for building Z39.50, SRU, and related library-search clients and servers. ### Project history YAZ++ grew out of the long-running YAZ ecosystem, which Index Data describes as a toolkit for Z39.50, SRW/SRU, and Solr-oriented information retrieval. The YAZ repository traces that base toolkit back to 1995, while the YAZ++ documentation frames this package as the C++ layer for using YAZ from C++ rather than C. The ZOOM C++ binding became part of YAZ++ early: the ZOOM site noted on 2002-10-24 that the YAZ implementation was available as part of the new YAZ++ toolkit and included in YAZ++ releases from 0.4 onward. Later YAZ++ documentation says versions 0.7 and newer added SRU support. The modern GitHub repository was created on 2016-01-06 as a public mirror/workspace for a codebase that was already established in the library-technology world. Its README still presents the package in classic toolkit terms: a C++ library, C++ headers, DocBook documentation, Windows build files, and small example clients and servers. ### Adoption history YAZ++ adoption is mostly within the library, catalog, and metadata-search niche rather than general-purpose C++ development. The Library of Congress Z39.50 software resources page lists YAZ / YAZ++ as C/C++ programmer toolkits for Z39.50/SRW/SRU clients and servers, reflecting its role in standards-based library interoperability. The package is useful where organizations already rely on YAZ but want C++ objects and ZOOM abstractions. That adoption pattern is narrow but durable: a small toolkit can stay packaged for years because Z39.50/SRU infrastructure in libraries changes slowly and values protocol compatibility. ### How it is used Developers use YAZ++ to build Z39.50 or SRU clients and servers in C++. The package includes examples such as a basic client, a basic server, and a ZOOM client, and the API documentation describes socket observers, PDU observers, query abstractions, and higher-level client/server objects around YAZ data structures. In practice, YAZ++ sits below discovery applications, proxies, and catalog integrations. It is not a user-facing search program so much as a packaged protocol library for developers who need to speak established library-retrieval protocols. ### Why package nerds care YAZ++ is package-nerd significant because it is a small binding package for a very specific standards ecosystem. It shows why package managers keep niche libraries alive: the audience is small, but the consumers need reproducible builds for long-lived institutional infrastructure. It also illustrates the packaging split common in C/C++ protocol stacks: the base C toolkit, language bindings, examples, generated documentation, and downstream packages all matter separately even when the visible command-line surface is tiny. ### Timeline - 1995: Index Data's YAZ toolkit lineage begins, providing the C base that YAZ++ wraps. - 2002-10-24: The ZOOM C++ site documents the YAZ implementation as part of the new YAZ++ toolkit and included from YAZ++ 0.4 onward. - YAZ++ 0.7 era: The YAZ++ introduction notes SRU support in later versions, starting with 0.7 and newer. - 2016-01-06: The public GitHub repository for indexdata/yazpp is created. ### Related projects - Related projects include YAZ, YAZ Proxy, ZOOM, ZOOM-Perl, yaz4j, PHP/YAZ, Zebra, Z39.50, SRU/SRW, Solr, DocBook, and the Library of Congress Z39.50 standards ecosystem. ### Sources - - - - - - - - ## Security Notes No matching local secret-handling manifest was found for yazpp. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** yazpp - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Ubuntu apt - libyazpp-dev - 1.6.5-0ubuntu4: normalized package name match | Ubuntu 24.04 LTS package indexes: libyazpp-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Development libraries for YAZ++ and ZOOM | http://www.indexdata.dk/yazplusplus/ - Ubuntu apt - libyazpp-doc - 1.6.5-0ubuntu4: normalized package name match | Ubuntu 24.04 LTS package indexes: libyazpp-doc from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Documentation for YAZ++ | http://www.indexdata.dk/yazplusplus/ - Ubuntu apt - libyazpp6 - 1.6.5-0ubuntu4: normalized package name match | Ubuntu 24.04 LTS package indexes: libyazpp6 from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | YAZ++ and ZOOM library | http://www.indexdata.dk/yazplusplus/ - MacPorts - yazpp: normalized package name match | MacPorts ports tree: net/yazpp/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [yaz](https://www.automicvault.com/pkg/brew/yaz/) - Runtime dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [metaproxy](https://www.automicvault.com/pkg/brew/metaproxy/) - Popular package that depends on this formula. - [ctemplate](https://www.automicvault.com/pkg/brew/ctemplate/) - Shares av.db curated category or tags: c-plus-plus, cli, developer-tools, libraries, library. - [ada-url](https://www.automicvault.com/pkg/brew/ada-url/) - Shares av.db curated category or tags: cli, developer-tools, libraries, library. - [cgal](https://www.automicvault.com/pkg/brew/cgal/) - Shares av.db curated category or tags: cli, developer-tools, libraries, library. - [curlpp](https://www.automicvault.com/pkg/brew/curlpp/) - Shares av.db curated category or tags: cli, developer-tools, libraries, library. - [flickcurl](https://www.automicvault.com/pkg/brew/flickcurl/) - Shares av.db curated category or tags: cli, developer-tools, libraries, library. - [fonttools](https://www.automicvault.com/pkg/brew/fonttools/) - Shares av.db curated category or tags: cli, developer-tools, libraries, library. - [glib](https://www.automicvault.com/pkg/brew/glib/) - Shares av.db curated category or tags: cli, developer-tools, libraries, library. - [pazpar2](https://www.automicvault.com/pkg/brew/pazpar2/) - Local package facts share a topical domain.
